Transmission Spectrum of the Benchmark Temperate Exo-Neptune TOI-1231 b
Subhajit Sarkar, Nikku Madhusudhan, Lorenzo Pica-Ciamarra +4
The JWST is revolutionizing our understanding of the temperate sub-Neptune population through atmospheric spectroscopy. The nature of these planets remains debated, as their bulk p…
Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources
T. Cavalié, R. Moreno, C. Lefour +16
Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. This work aims…
A JWST Transmission Spectrum of the Temperate Sub-Neptune TOI-732 c
Frances E. Rigby, Nikku Madhusudhan, Subhajit Sarkar +3
In recent years, JWST has facilitated detections of carbon-bearing molecules in the atmospheres of temperate sub-Neptunes orbiting M dwarfs, ushering in a new era in the characteri…
The impact of organic hazes and graphite on the observation of CO2-rich sub-Neptune atmospheres
Haixin Li, Chao He, Sai Wang +9
Many sub-Neptune and super-Earth exoplanets are expected to develop metal-enriched atmospheres due to atmospheric loss processes such as photoevaporation or core-powered mass loss.…
Formation of organic hazes in CO-rich sub-Neptune atmospheres within the graphite-stability regime
Sai Wang, Zhengbo Yang, Chao He +10
Super-Earths and sub-Neptunes are the most common exoplanets, with a "radius valley" suggesting that super-Earths may form by shedding sub-Neptunes' gaseous envelopes. Exoplanets t…
