Carbon Cycle Imbalances on Arid Terrestrial Planets with Implications for Venus
Haskelle T. White-Gianella, Joshua Krissansen-Totton
Arid terrestrial exoplanets are potentially abundant and are thus interesting targets in the search for life. In particular, M-dwarf planets such as those in the TRAPPIST-1 system…
Growth and thermal evolution of icy planetesimals
Jun Kimura, Ryusei Satoh, Kentaro Terada +1
Icy planetesimals are likely to supply volatiles to terrestrial planets and serve as building blocks of icy bodies in the outer Solar System. Samples from the C-type asteroid Ryugu…
Observation of an Accreting Planetary-Mass Companion with Signs of Disk-Disk Interaction in Orion
Emilie Vila, Paul Amiot, Olivier Berné +11
Young ( Myr) planetary-mass companions (PMCs) provide valuable insights into the formation and early evolution of planetary systems. To date, only a dozen such objects…
Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets
Joshua Krissansen-Totton, Anna Grace Ulses, Maxwell Frissell +21
Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insuf…
Modern Earth-like Chemical Disequilibrium Biosignatures Are Challenging To Constrain Through Spectroscopic Retrievals
Amber Young, Tyler Robinson, Joshua Krissansen-Totton +4
Robust exoplanet characterization studies are underway, and the community is looking ahead toward developing observational strategies to search for life beyond our solar system. Wi…
The erosion of large primary atmospheres typically leaves behind substantial secondary atmospheres on temperate rocky planets
Joshua Krissansen-Totton, Nicholas Wogan, Maggie Thompson +1
Exoplanet exploration has revealed that many$\unicode{x2013}$perhaps most$\unicode{x2013}$terrestrial exoplanets formed with substantial H-rich envelopes, seemingly in contrast…
