New and Updated Rossiter-McLaughlin Measurements for Three Hot Jupiter-Hosting M Dwarfs
Drew Weisserman, Ryan Cloutier, Alexandra Rochon +12
Evidence suggests that Kozai-Lidov high-eccentricity migration (HEM) is the dominant migration channel for short-period Giant Exoplanets around M dwarf Stars (GEMS). However, it is…
The MegaWave Radio Surveyor
T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40
Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…
Preparing for the Early eVolution Explorer: The Impact of Flare Temperature on Ozone Column Depth in Earth-Like Atmospheres
Jaime S. Crouse, Nicholas F. Wogan, Ward S. Howard +4
Atmospheric photochemical models incorporating the impacts of stellar flares often assume a 9,000 K spectrum at ultraviolet-optical wavelengths. Recent multiwavelength observ…
Preparing for the Early eVolution Explorer: Photometric Diagnostics of Magnetospheric Accretion Geometry in Young Stellar Objects
Laura Venuti, Connor E. Robinson, Ann Marie Cody +13
The inner disk truncation radius, , plays a crucial role in the regulation of star-disk interaction and the early evolution of star-disk-planet systems; however, measuring thi…
Exoplanet System Architecture: Sculpting the Inner Regions
Mark R. Swain, Geoffrey Bryden, Jonathan C. Tan +14
In this study, we seek to improve our understanding of the competing roles of disk-driven and planet-planet dynamical migration in sculpting planetary system architecture in the in…
The Effects of M Star Age Dependent Ultraviolet Emission on Detecting and Interpreting Exoplanet Biosignatures
C. Evan Davis, Victoria S. Meadows, Evgenya L. Shkolnik +5
Given their abundance and observational advantages, M stars will arguably be the best candidates for characterizing and searching for biosignatures on terrestrial exoplanets in the…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Preparing for the Early eVolution Explorer: Detecting the Primordial, Transiting Exoplanet Population
George Zhou, James G. Rogers, Jennifer A. Burt +17
The close-in small planet population may be formed either with hydrogen/helium dominated envelopes or with water-rich interiors. Both scenarios reproduce the present day planet pop…
The Range of Cumulative XUV Flux on GJ 1132 b
Rory Barnes, Laura N. R. do Amaral, Jessica Birky +4
We investigate the plausible history of the XUV luminosity evolution of the planet-hosting M4 star GJ 1132 (~0.2 solar masses) to infer the cumulative incident XUV flux intercepted…
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…
