The Early Career Astrobiology Workforce Under Strain Survey Evidence from 2025-2026
Katherine Dzurilla, Gabby Rizzo, Perianne Johnson +3
A survey of self identified early career astrobiologists was organized by the NOW early career group FLOW and the Scientific Society of Astrobiology. During November 2025 to Februa…
Nitrogen Loss from Pluto's Birth to the Present Day via Atmospheric Escape, Photochemical Destruction, and Impact Erosion
Perianne E. Johnson, Leslie A. Young, David Nesvorny +1
We estimate the loss of nitrogen from Pluto over its lifetime, including the giant planet instability period, which we term the "Wild Years." We analyze the orbital migration of 53…
Candidate Distant Trans-Neptunian Objects Detected by the New Horizons Subaru TNO Survey
Wesley C. Fraser, Simon B. Porter, Lowell Peltier +41
We report the detection of 239 trans-Neptunian Objects discovered through the on-going New Horizons survey for distant minor bodies being performed with the Hyper Suprime-Cam mosai…
New Constraints on Pluto's Sputnik Planitia Ice Sheet from a Coupled Reorientation-Climate Model
Perianne E. Johnson, James T. Keane, Leslie A. Young +1
We present a coupled reorientation and climate model, to understand how true polar wander (TPW) and atmospheric condensation worked together to create the Sputnik Planitia (SP) ice…
Modeling Pluto's Minimum Pressure: Implications for Haze Production
Perianne E. Johnson, Leslie A. Young, Silvia Protopapa +6
Pluto has a heterogeneous surface, despite a global haze deposition rate of ~1 micrometer per orbit (Cheng et al., 2017; Grundy et al., 2018). While there could be spatial variatio…
