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 role of the Hubble Space Telescope in advancing our understanding of atmospheric escape in exoplanets

Leonardo A. Dos Santos, Arika Egan, Kevin France +14

An important evolutionary pathway for planetary atmospheres is escape to space, which has been studied on Earth and Mars for several decades and more recently in exoplanets. A part…

The Ultraviolet View of Star and Planet Formation: Disks, Accretion, and Outflows with the Hubble Space Telescope into the 2030s

Kevin France, Eric Gaidos, Catherine Espaillat +2

The spatial distribution and lifetime of molecular gas in the inner regions of young circumstellar disks are key to understanding the formation of planetary systems. Gas-rich disks…

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…

Six-yr SPIRou monitoring of the young planet-host dwarf AU Mic

J. -F. Donati, P. I. Cristofari, C. Moutou +10

In this paper we revisit our spectropolarimetric and velocimetric analysis of the young M dwarf AU Mic based on data collected with SPIRou at the Canada-France-Hawaii telescope, ov…
