Search for radio emission from the exoplanets Qatar-1b and WASP-80b near 150 MHz using the Giant Metrewave Radio Telescope
D. A. Green, N. Madhusudhan
We present radio observations made towards the exoplanets Qatar-1b and WASP-80b near 150~MHz with the Giant Meterwave Radio Telescope. These targets are relatively nearby irradiate…
The Hubble PanCET Program: A Metal-rich Atmosphere for the Inflated Hot Jupiter HAT-P-41b
Kyle B. Sheppard, Luis Welbanks, Avi Mandell +14
We present a comprehensive analysis of the 0.3--5\,m transit spectrum for the inflated hot Jupiter HAT-P-41b. The planet was observed in transit with Hubble STIS and WFC3 as par…
On the Temperature Profiles and Emission Spectra of Mini-Neptune Atmospheres
Anjali A. A. Piette, Nikku Madhusudhan
Atmospheric observations of mini-Neptunes orbiting M-dwarfs are beginning to provide constraints on their chemical and thermal properties, while also providing clues about their in…
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…
A Featureless Infrared Transmission Spectrum for the Super-Puff Planet Kepler-79d
Yayaati Chachan, Daniel Jontof-Hutter, Heather A. Knutson +12
Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ( M) and…
Considerations for Atmospheric Retrieval of High-Precision Brown Dwarf Spectra
Anjali A. A. Piette, Nikku Madhusudhan
Isolated brown dwarfs provide remarkable laboratories for understanding atmospheric physics in the low-irradiation regime, and can be observed more precisely than exoplanets. As su…
