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…

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),…
