Another ExoMol announcement: IR/Vis/UV line list for YO (Yttrium oxide) is available at exomol.com/data/molecules…, also provided with opacities. The manuscript by Sergey Yurchenko et al. arxiv.org/abs/2308.04173 is currently under review.

Neptune's variable clouds linked AGAIN to the solar cycle (Wes Lockwood first suggested this more than 20 years ago; he and I also discussed in it in two papers in 2007). But this new work is a GREAT paper and data set (W. M. Keck Observatory Hubble)! hubblesite.org/contents/news-…

Let us know if we should compute a line list for CH3+!

We found the methane! (in transiting planet atmospheres!) In transmission and emission! #JWST arxiv.org/abs/2309.04042 A great paper from the MANATEE collaboration, led by @taylorbell275!

The Webb telescope has detected carbon dioxide and methane in the atmosphere of exoplanet K2-18 b, a potentially habitable world over 8 times bigger than Earth. Webb’s data suggests the planet might be covered in ocean, with a hydrogen-rich atmosphere: go.nasa.gov/3sGKNLe

I’m pretty sure this is an accurate one-panel guide to Spectral Modelling, be sure to let us know if we got anything wrong #Chemistry #Modelling #LondonFashionWeek

On the cover! #COSY_Science Akexander O. Mitrushchenkov and María Pilar de Lara-Castells doi.org/10.1002/cphc.2…

The European project ATMOS participates in #nightspain #huelva #unihuelva. In this activity it was explained the role of the molecules in the Earth atmosphere and other environments.

Line list updates: The LaO line list has been extended to include the A-X band by Bernath et al. iopscience.iop.org/article/10.384… , see exomol.com/data/molecules…

HUGE THANKS to @tartuobs for hosting a fantastic Ariel Consortium Meeting this past week! 🇪🇪

ExoMol tea journal club. Today's Spectrle: what molecule is it? Clue: it is in ExoMol and a diatomic

"By comparing models based on opacities from the limited number of molecules available in 2008 with models based on a more extensive number of molecules available in ExoMol, we concluded that limitation in the classical 2008-grid did not affect the accuracy of the models"🤔

#exomoltea Today's spectrle 😜 What @exomol molecule is this? Hint: it is a diatomic.

It is sad news of Prof Kamil Sarka passing. I was lucky enough to meet him at conferences and even more so to know his fundamental work on theoretical molecular spectroscopy 😥
