Coupled Day-Night Models of Exoplanetary Atmospheres
Siddharth Gandhi, Adam S. Jermyn
We provide a new framework to model the day side and night side atmospheres of irradiated exoplanets using 1-D radiative transfer by incorporating a self-consistent heat flux carri…
Seeing above the Clouds with High Resolution Spectroscopy
Siddharth Gandhi, Matteo Brogi, Rebecca K. Webb
In the last decade ground based high resolution Doppler spectroscopy (HRS) has detected numerous species in transiting and non-transiting hot Jupiters, and is ideally placed for at…
Neutral Cr and V in the atmosphere of ultra hot jupiter WASP-121 b
Maya Ben-Yami, Nikku Madhusudhan, Samuel H. C. Cabot +4
Ultra hot jupiters (UHJs), giant exoplanets with equilibrium temperatures above 2000 K, are ideal laboratories for studying metal compositions of planetary atmospheres. At these te…
Assessing Spectra and Thermal Inversions due to TiO in Hot Jupiter Atmospheres
Anjali A. A. Piette, Nikku Madhusudhan, Laura K. McKemmish +3
Recent detections of thermal inversions in the dayside atmospheres of some hot Jupiters are motivating new avenues to understand the interplay between their temperature structures…
H- and Dissociation in Ultra-hot Jupiters: A Retrieval Case Study of WASP-18b
Siddharth Gandhi, Nikku Madhusudhan, Avi Mandell
Atmospheres of a number of ultra-hot Jupiters (UHJs) with temperatures 2000~K have been observed recently. Many of these planets show largely featureless thermal spectra i…
Molecular Cross Sections for High Resolution Spectroscopy of Super Earths, Warm Neptunes and Hot Jupiters
Siddharth Gandhi, Matteo Brogi, Sergei N. Yurchenko +9
High resolution spectroscopy (HRS) has been used to detect a number of species in the atmospheres of hot Jupiters. Key to such detections is accurately and precisely modelled spect…
A weak spectral signature of water vapour in the atmosphere of HD 179949 b at high spectral resolution in the L-band
Rebecca K. Webb, Matteo Brogi, Siddharth Gandhi +5
High resolution spectroscopy (R > 20,000) is currently the only known method to constrain the orbital solution and atmospheric properties of non-transiting hot Jupiters. It does so…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
Detection of neutral atomic species in the ultra-hot jupiter WASP-121b
Samuel H. C. Cabot, Nikku Madhusudhan, Luis Welbanks +2
The class of ultra-hot Jupiters comprises giant exoplanets undergoing intense irradiation from their host stars. They have proved to be a particularly interesting population for th…
