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…
Formation and evolution pathways of planets. I. Comparison between theory and observations
Yasuhiro Hasegawa, Renyu Hu, Amine Bouzerzour
Discoveries of numerous exoplanets by various methods enable detailed characterization including bulk density. Formation and evolution pathways of planets can thus be probed in the…
Investigating the Role of Protostellar Variability with PRIMA Using Monte Carlo Simulations
Rachel R. Lee, Cara Battersby, Aleksandra Kuznetsova +5
Evidence suggests that protostellar outbursts likely play a critical role in the stellar mass assembly process, but the extent of this contribution is not well understood. Using th…
Volcanic Satellites Tidally Venting Na, K, SO2 in Optical & Infrared Light
Apurva V. Oza, Andrea Gebek, Moritz Meyer zu Westram +19
Recent infrared spectroscopy from the James Webb Space Telescope (JWST) has spurred analyses of common volcanic gases such as carbon dioxide (CO2), sulfur dioxide (SO2), alongside…
Planetary waves can activate resonant drag instabilities in 3D dusty gaseous discs
Raúl O. Chametla, Yasuhiro Hasegawa, Gennaro D'Angelo
Resonant Drag Instabilities (RDIs) in protoplanetary discs are driven by the aerodynamic back-reaction of dust on gas and occur when the relative dust-gas motion resonate with a wa…
Review and prospects of hot exozodiacal dust research for future exo-Earth direct imaging missions
Steve Ertel, Tim D. Pearce, John H. Debes +12
Hot exozodiacal dust is dust in the innermost regions of planetary systems, at temperatures around 1000K to 2000K, and commonly detected by near-infrared interferometry. The phenom…
Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections
Yifan Zhou, Brendan P. Bowler, Aniket Sanghi +14
Understanding the processes of planet formation and accretion in young systems is essential to unraveling the initial conditions of planetary systems. The PDS 70 system, which host…
Widespread disruption of resonant chains during protoplanetary disk dispersal
Brad M. S. Hansen, Tze-Yeung Yu, Yasuhiro Hasegawa
We describe the evolution of low mass planets in a dispersing protoplanetary disk around a Solar mass star. The disk model is based on the results of Yu, Hansen & Hasegawa (2023),…
Predicting the Dominant Formation Mechanism of Multi-Planetary Systems
Cheyanne Shariat, Yasuhiro Hasegawa, Bradley M. S. Hansen +2
Most, if not all, sun-like stars host one or more planets, making multi-planetary systems commonplace in our galaxy. We utilize hundreds of multi-planet simulations to explore the…
Far-Infrared Luminosity Bursts Trace Mass Accretion onto Protostars
William J. Fischer, Cara Battersby, Doug Johnstone +6
Evidence abounds that young stellar objects undergo luminous bursts of intense accretion that are short compared to the time it takes to form a star. It remains unclear how much th…
