Discovery of 20 UV Emitting SNRs in M31 with UVIT
Denis Leahy, Christopher Monaghan, Sujith Ranasinghe
We present the first catalog of supernova remnants (SNRs) in M31 which exhibit diffuse ultraviolet (UV) emission. UV images of M31 were obtained by the Ultraviolet Imaging Telescop…
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…
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…
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,…
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…
