Today's spectrle 😜
What @exomol molecule is this? Hint: it is 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"🤔

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

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.

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

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
ALT A graphic titled “Exoplanet K2-18 b: Atmosphere Composition.” The graphic shows the spectra of the exoplanet K2-18 b from NIRISS and NIRSpec in the form of a graph, with the vertical y-axis labeled as Amount of Light Blocked and the horizontal axis labeled as Wavelength of Light (microns). The data is plotted as dots with vertical error bars. A jagged blue line running through the plot represents the best-fit model. There are semi-transparent magenta, red and green vertical columns also scattered across the plot, indicating where variations in the line represent the presence of methane, carbon dioxide, and dimethyl sulfide (combined with other molecules), respectively. Behind the graph is an illustration of the planet and star. The planet is a large fuzzy blue-ish sphere off to the right, taking up half of the background. The red star is smaller at the bottom left of the entire graphic.

We found the methane! (in transiting planet atmospheres!) In transmission and emission! #JWST

A great paper from the MANATEE collaboration, led by @taylorbell275!

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 (@keckobservatory @NASAHubble)! hubblesite.org/contents/news…

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

@ExoMol announcement: new line list for ZrO by Armando Perri, Fadia Taher and @laura_mckemmish. See the MNRAS paper doi.org/10.1093/mnras/stad21… and line lists for six isotopologues of ZrO exomol.com/data/molecules/Zr…. Enjoy!
