How Deep Is the Ocean? Exploring the phase structure of water-rich sub-Neptunes
Matthew C. Nixon, Nikku Madhusudhan
Understanding the internal structures of planets with a large HO component is important for the characterisation of sub-Neptune planets. The finding that the mini-Neptune K2-18…
A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
R. Luque, L. M. Serrano, K. Molaverdikhani +63
We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54+-0.03 Msun) detected during Sector 10 o…
Assessment of Supervised Machine Learning for Atmospheric Retrieval of Exoplanets
Matthew C. Nixon, Nikku Madhusudhan
Atmospheric retrieval of exoplanets from spectroscopic observations requires an extensive exploration of a highly degenerate and high-dimensional parameter space to accurately cons…
HST/STIS transmission spectrum of the ultra-hot Jupiter WASP-76 b confirms the presence of sodium in its atmosphere
C. von Essen, M. Mallonn, S. Hermansen +4
We present an atmospheric transmission spectrum of the ultra-hot Jupiter WASP-76 b by analyzing archival data obtained with the Space Telescope Imaging Spectrograph (STIS) on board…
The interior and atmosphere of the habitable-zone exoplanet K2-18b
Nikku Madhusudhan, Matthew C. Nixon, Luis Welbanks +2
Exoplanets orbiting M dwarfs present a valuable opportunity for their detection and atmospheric characterisation. This is evident from recent inferences of HO in such atmospher…
