Carbon-bearing Molecules in a Possible Hycean Atmosphere
Nikku Madhusudhan, Subhajit Sarkar, Savvas Constantinou +3
The search for habitable environments and biomarkers in exoplanetary atmospheres is the holy grail of exoplanet science. The detection of atmospheric signatures of habitable Earth-…
Robustness Measures for Molecular Detections using High-Resolution Transmission Spectroscopy of Exoplanets
Connor J. Cheverall, Nikku Madhusudhan, Måns Holmberg
Ground-based high-resolution transmission spectroscopy has emerged as a promising technique for detecting chemicals in transiting exoplanetary atmospheres. Despite chemical inferen…
A precise blue-optical transmission spectrum from the ground: Evidence for haze in the atmosphere of WASP-74b
Petros Spyratos, Nikolay K. Nikolov, Savvas Constantinou +5
We report transmission spectroscopy of the bloated hot Jupiter WASP-74b in the wavelength range from 4000 to 6200 Å. We observe two transit events with the Very Large Telescope FOc…
HyDRo: Atmospheric Retrieval of Rocky Exoplanets in Thermal Emission
Anjali A. A. Piette, Nikku Madhusudhan, Avi M. Mandell
Emission spectroscopy is a promising technique to observe atmospheres of rocky exoplanets, probing both their chemistry and thermal profiles. We present HyDRo, an atmospheric retri…
C/O and O/H Ratios Suggest Some Hot Jupiters Originate Beyond the Snow Line
John M. Brewer, Debra A. Fischer, Nikku Madhusudhan
The elemental compositions of planet hosting stars serve as proxies for the primordial compositions of the protoplanetary disks within which the planets form. The temperature profi…
Atmospheric Compositions of Three Brown Dwarfs and Implications for their Formation Conditions
Nikku Madhusudhan, Dániel Apai, Siddharth Gandhi
The formation mechanisms and chemical compositions of brown dwarfs likely span a diverse range. If they are formed predominantly in isolation by gravitational collapse like dwarf s…
