JWST NIRSpec G395H Transmission Spectra of Two Similar Sub-Neptunes in the TOI-125 System
Yiwei Chai, Néstor Espinoza, Chloe Fisher +10
The James Webb Space Telescope (JWST) has enabled the first in-depth characterisations of sub-Neptune atmospheres, revealing a diversity of chemical compositions and cloud properti…
The Effect of Atmospheric Chemistry on the Optical Geometric Albedos of Hot Jupiters
K. D. Jones, B. M. Morris, K. Heng
We investigate the geometric albedos of hot Jupiters by comparing observational data from space telescopes TESS, Kepler, CoRoT, and CHEOPS against theoretical models. The study aim…
JWST NIRSpec finds no clear signs of an atmosphere on TOI-1685 b
Chloe E. Fisher, Matthew J. Hooton, Amélie Gressier +21
Determining the prevalence of atmospheres on terrestrial planets is a core objective in exoplanetary science. While M dwarf systems offer a promising opportunity, conclusive observ…
Hot Rocks Survey IV: Emission from LTT 3780 b is consistent with a bare rock
Natalie H. Allen, Néstor Espinoza, Hannah Diamond-Lowe +19
It is an open question whether small planets around M dwarfs are able to maintain atmospheres. The Hot Rocks Survey aims to address this question by observing 9 rocky exoplanets or…
Differentiable Modeling of Planet and Substellar Atmosphere: High-Resolution Emission, Transmission, and Reflection Spectroscopy with ExoJAX2
Hajime Kawahara, Yui Kawashima, Shotaro Tada +11
Modeling based on differentiable programming holds great promise for astronomy, enabling advanced techniques such as gradient-based posterior sampling and optimization. This paradi…
Observations of scattered light from exoplanet atmospheres
Brett M. Morris, Kevin Heng, Daniel Kitzmann
Optical phase curves of hot Jupiters can reveal global scattering properties. We implement a Bayesian inference framework for optical phase curves with flux contributions from: ref…
Hunt for Starspots in HARPS Spectra of G and K Stars
Brett M. Morris, H. Jens Hoeijmakers, Daniel Kitzmann +1
We present a method for detecting starspots on cool stars using the cross-correlation function (CCF) of high resolution molecular spectral templates applied to archival high-resolu…
