Now that we know Harry Kane will miss at least one and a half month of competition, we have to talk about his possible subs at Tottenham.This Tuesday was mostly led by really bad news coming from the Tottenham Hotspur camp, as the extent of Harry Kane’s ankle injury was disclosed and the Englishman will miss at least one and a half months of competition.All the Spurs fans are really worried about the repercussions that this may bring, because we are talking about one of the most important strikers in the world right now and they won’t have him for an important amount of matches this season.The most worrying part of all this will be the first Champions League against Borussia Dortmund, which Kane will miss without question and leaves Mauricio Pochettino with a huge dilemma of who might be able to replace the skipper.There are three options that the Argentine manager is considering, we are going through all of them and give you the details in this article.Game day! #COYS pic.twitter.com/B003gtKwVo— Heung-Min Son (@OfficiaISonny) September 16, 2017Son Heung MinThe South Korean forward is the natural option to replace Harry Kane, he is the other Tottenham Hotspur’s player who has been on fire this season and there is no question that he would be the ideal candidate to take Harry Kane’s place as the offensive leader for the time the captain won’t be available.But there is a major problem with Son, he traveled to the United Arab Emirates this week to represent his country in this year’s Asia Cup.South Korea is considered a favorite of this competition and they are expected to go all the way to the final, if that happens then Son would return until after February 1st.The forward playing all the tournament with South Korea means that he will likely miss the upcoming five matches for Spurs, but he will certainly be back in time to play the Champions League’s round of 16 against Borussia Dortmund.⚡️⚡️⚡️⚡️⚡️⚡️⚡️💥💥💥💥 pic.twitter.com/5KpLCcsjsI— Lucas Moura (@LucasMoura7) August 27, 2018Lucas MouraWhen Son is not around, Mauricio Pochettino could take the option of playing with Lucas Moura as a striker.Pochettino admits Wanyama remains in his Spurs plans Manuel R. Medina – September 14, 2019 Kenyan international, Victor Wanyama, was the protagonist of a summer transfer saga, but in the end, he is set to stay at Tottenham Hotspur.The Brazilian winger has proved his worth this season with great performances against worthy opponents, but he is far from being a striker like Son or Kane truly are.However, Moura could bring something entirely different to Tottenham and Mauricio Pochettino could opt to play with no natural striker down the middle.This option does seem a little more farfetched but the Argentine manager does seem stuck in a tight spot with this decision, while there are other options like Dele Alli, the manager might end up deciding to use the only centre-forward he has to properly replace Harry Kane.Training session #COYS #THFC pic.twitter.com/8VTSvaHIpA— Fernando Llorente (@llorentefer19) January 11, 2019Fernando LlorenteThe odds that an opportunity like this could present itself for Fernando Llorente were pretty slim, but this is how destiny and football work sometimes.The Spaniard has gone from not being considered to play for Tottenham at all, to one of the very first options that Mauricio Pochettino is considering to replace Harry Kane in the next one and a half month of all competitions.There is no question that the Spaniard does have the quality to replace the Englishman, the only problem is the lack of participation which might get him to start a bit slow in the first few matches.However, Llorente had been waiting for this big break for a long time and he won’t let this opportunity get past him at all.Delivering good performances while Harry Kane is out of commission, might be the best way in which Tottenham Hotspur could increase this player’s value for the next transfer window.Injuries are part of the game but no-one will be working harder to get back fit.

Explore further Planetary influences on young stellar disks (Phys.org)—An international team of astronomers, led by Markus Janson of Stockholm University in Sweden, has discovered mysterious sharp symmetric features around young double star, named AK Sco. The discovery is baffling scientists as they are still unsure about the nature of these features, pondering the possibilities that they are highly eccentric rings or two separate spiral arms in the disk around the star. Moreover, these features may have been caused by circumbinary planets interacting with the disk. The results were published on Dec. 14 in the arXiv journal. AK Sco, located about 460 light years from Earth, is a spectroscopic binary star in the Upper Centaurus–Lupus (UCL) stellar association. It is a relatively young system, at least in astronomical terms, as scientists estimate it to be from 10 to 20 million years old. Spectroscopic binaries are systems in which the stars are so close together that they appear as a single star even in a telescope. The only evidence of a binary star comes from the Doppler effect on its emitted light. Periodic Doppler shifts of the wavelengths of lines are seen in the spectrum, as the stars move through their orbits.Janson and his colleagues made the discovery using the European Southern Observatory’s (ESO) Very Large Telescope (VLT), located in Chile. The observations were conducted in April 2015 as a part of the Search for Planets Orbiting Two Stars (SPOTS) program. The scientists made use of the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument recently installed on VLT. SPHERE is a powerful planet finder and its objective is to detect and study new giant exoplanets orbiting nearby stars using a method known as direct imaging.Detecting the sharp features in near-infrared imaging of AK Sco’s disk was a surprise for the scientists as they expected to find rather exoplanets in the neighborhood. However, what they found, might not be planets at all.”We report the discovery of resolved scattered light emission from the circumbinary disk around the well-studied young double star AK Sco. The sharp morphology of the imaged feature is surprising, given the smooth appearance of the disk in its spectral energy distribution,” the astronomers wrote in the paper.They researchers have noticed that the central binary star has a semi-major axis of approximately 0.16 astronomical units or AU and that the disk appears to have a gap with an inner rim at 0.58 AU. The images of AK Sco obtained by the SPHERE instrument reveal that the system has ‘arms’ extending from each side of the central star almost symmetrically. The scientists also found out that these features constitute scattered radiation from off-axis material in the circumbinary disk.The mysterious sharp features could represent an eccentric ring of material surrounding a gap. The scientists note that such structures are often found in disks that contain rings of material with gaps inside them. However, other observations conducted by ESO’s Atacama Large Millimeter Array (ALMA) don’t support this theory.Another explanation taken into account by Janson and his colleagues is that these structures are spiral arms that could be induced through gravitational instability or through the influence of a planet or binary companion. These two spiral arms are wound in opposite directions—one unwinding clockwise and the other counter-clockwise. But the fact that the features are so apparently symmetric, speaks against this hypothesis.What is worth noticing, either of these scenarios mentioned earlier, may point to circumbinary exoplanets in the disk. The features could be created by one or several planets interacting with the disk.Whichever proposed theory is true, the authors of the paper highlight the importance of the new generation adaptive optics systems – like this installed on the SPHERE instrument – in the search of disks around stars. They hope that these features will detected more often in near future as a result of implementing new technology of observations. SPHERE high-contrast images of AK Sco.

With the SPHERE Extreme Adaptive Optics instrument, a good contrast can be achieved even at small (<300 mas) separations from bright stars, which enables studies of planets and disks in a separation range that was previously inaccessible. Here, we report the discovery of resolved scattered light emission from the circumbinary disk around the well-studied young double star AK Sco, at projected separations in the ~13—40 AU range. The sharp morphology of the imaged feature is surprising, given the smooth appearance of the disk in its spectral energy distribution. We show that the observed morphology can be represented either as a highly eccentric ring around AK Sco, or as two separate spiral arms in the disk, wound in opposite directions. The relative merits of these interpretations are discussed, as well as whether these features may have been caused by one or several circumbinary planets interacting with the disk.
