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…

An Outer Giant Planet or Brown Dwarf in the 51 Pegasi System?

Marvin Morgan, Brendan P. Bowler, Kyle Franson +15

51 Pegasi harbors the first confirmed extrasolar planet orbiting a Sun-like star. Decades of continued radial velocity (RV) observations have since uncovered signatures of an addit…

The SPIRou Legacy Survey: Detection of a nearby world orbiting in the habitable zone of Gl725B achieved by correcting strong telluric contamination in near-infrared radial velocities with WAPITI

M. Ould-Elhkim, C. Moutou, J. -F. Donati +15

M dwarfs are prime targets in the search for exoplanets because of their prevalence and because low-mass planets can be better detected with radial velocity (RV) methods. In partic…

On the diversification and dissipation of protoplanetary disks

Eric Gaidos, Lukas Gehrig, Manuel Güdel

Protoplanetary disk evolution exhibits trends with stellar mass, but also diversity of structure, and lifetime, with implications for planet formation and demographics. We show how…
