The Exospace Weather Frontier
R. O. Parke Loyd, Evgenya L. Shkolnik, Joseph Lazio +26
Space weather is among the most powerful and least understood forces shaping planetary atmospheres. In our Solar System, we observe its effects directly: atmospheric escape, chemic…
TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc
Adalyn Gibson, Meredith A. MacGregor, Ward S. Howard +9
We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling c…
Constraining the Mass Loss and the Kinetic Energy of Solar Coronal Mass Ejections with Far-Ultraviolet Flares
Nuri Park, Evgenya L. Shkolnik, Joe Llama
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres. For instance, strong…
Lyman-Alpha Emission from K and M Dwarfs: Intrinsic Profiles, Variability, and Flux in the Habitable Zone
Sarah Peacock, Travis S. Barman, R. O. Parke Loyd +4
Lyman- (Ly) is the most prominent ultraviolet emission line in low-mass stars, playing a crucial role in exoplanet atmospheric photochemistry, heating, and escape. However, i…
Aligned Stellar Obliquities for Two Hot Jupiter-hosting M Dwarfs Revealed by MAROON-X: Implications for Hot Jupiter Formation
Drew Weisserman, Erik Gillis, Ryan Cloutier +14
Hot Jupiters (HJs) are less common around early M dwarfs than around AFGK stars, suggesting that HJs may form and/or migrate via distinct pathways around different type…
The SPACE Program. I. The featureless spectrum of HD 86226 c challenges sub-Neptune atmosphere trends
K. Angelique Kahle, Jasmina Blecic, Reza Ashtari +26
Sub-Neptune exoplanets are the most abundant type of planet known today. As they do not have a Solar System counterpart, many open questions exist about their composition and forma…
Building SPARCS, an Ultraviolet Science CubeSat for Exoplanet Habitability Studies, Technology Advancements, and Mission Training
Evgenya L. Shkolnik, David R. Ardila, Logan Jensen +17
The Star-Planet Activity Research CubeSat (SPARCS) is a NASA-funded 6U-CubeSat mission designed to monitor ultraviolet (UV) radiation from low-mass stars. These stars' relatively h…
Detecting and characterising the magnetic field of exoplanets
A. Strugarek, S. V. Berdyugina, V. Bourrier +25
Magnetic fields play a crucial role in planetary evolution and habitability. While the intrinsic magnetic fields of solar system planets are relatively well understood, the magneti…
