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…
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…
Water vapor as a probe of the origin of gas in debris disks
Yasuhiro Hasegawa, Riouhei Nakatani, Isabel Rebollido +5
Debris disks embrace the formation and evolution histories of planetary systems. Recent detections of gas in these disks have received considerable attention, as its origin ties up…
Secret of Longevity: Protoplanetary Disks as a Source of Gas in Debris Disks
Wataru Ooyama, Riouhei Nakatani, Takashi Hosokawa +2
While protoplanetary disks (PPDs) are generally thought to disperse within several million years, recent observations have revealed gas in their older counterparts, debris disks. T…
Broadening the Canonical Picture of EUV-Driven Photoevaporation of Accretion Disks
Riouhei Nakatani, Neal J. Turner, Shinsuke Takasao
Photoevaporation driven by hydrogen-ionizing radiation, also known as extreme-ultraviolet (EUV), profoundly shapes the lives of diverse astrophysical objects. Focusing here mainly…
