GJ 3929 b as the First Complete Rocky Worlds DDT Data Set
Nicholas J. Connors, Christopher Monaghan, Björn Benneke +3
Despite their large abundance, it is still unknown whether and under what conditions rocky planets around M dwarf stars can host atmospheres. This open question motivated the on-go…
Uniform Reinterpretation of Rocky Exoplanet Secondary Eclipse Observations and the Impact of Stellar and Orbital Uncertainties
Christopher Monaghan, Björn Benneke, Nicholas J. Connors +2
Secondary eclipse observations are a powerful way to investigate whether or not a rocky exoplanet hosts an atmosphere, as an atmospheric presence would transport heat to the nights…
Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b
Louis-Philippe Coulombe, Björn Benneke, Joshua Krissansen-Totton +25
The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the ex…
Uniform Reanalysis of JWST MIRI 15μm Exoplanet Eclipse Observations using Frame-Normalized Principal Component Analysis
Nicholas J. Connors, Christopher Monaghan, Björn Benneke +1
JWST MIRI 15 micron time-series eclipse photometry presents a powerful way to probe for the presence of atmospheres on low-temperature rocky exoplanets orbiting nearby stars. Here,…
Low 4.5 μm Dayside Emission Disfavors a Dark Bare-Rock scenario for the Hot Super-Earth TOI-431 b
Christopher Monaghan, Pierre-Alexis Roy, Björn Benneke +13
The full range of conditions under which rocky planets can host atmospheres remains poorly understood, especially in the regime of close-in orbits around late-type stars. One way t…
