Preparing for the Early eVolution Explorer: Photometric Diagnostics of Magnetospheric Accretion Geometry in Young Stellar Objects
Laura Venuti, Connor E. Robinson, Ann Marie Cody +13
The inner disk truncation radius, , plays a crucial role in the regulation of star-disk interaction and the early evolution of star-disk-planet systems; however, measuring thi…
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…
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…
Mass, Gas, and Gauss around a T Tauri Star with SPIRou
J. -F. Donati, E. Gaidos, C. Moutou +4
Studies of young planets help us understand planet evolution and investigate important evolutionary processes such as atmospheric escape. We monitored IRAS 04125+2902, a 3 Myr-old…
Do accretion-powered stellar winds help spin down T Tauri stars?
Lukas Gehrig, Eric Gaidos, Laura Venuti +2
How T Tauri stars remain slowly rotating while still accreting material is a long-standing puzzle. Current models suggest that these stars may lose angular momentum through magneto…
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…
SPIRou observations of the young planet-hosting star PDS 70
J. -F. Donati, P. I. Cristofari, S. H. P. Alencar +14
This paper presents near-infrared spectropolarimetric and velocimetric observations of the young planet-hosting T Tauri star PDS 70, collected with SPIRou at the 3.6m Canada-France…
Investing in the Unrivaled Potential of Wide-Separation Sub-Jupiter Exoplanet Detection and Characterisation with JWST -- Strategic Exoplanet Initiatives with HST and JWST White Paper
Aarynn L. Carter, Rachel Bowens-Rubin, Per Calissendorff +15
We advocate for a large scale imaging survey of nearby young moving groups and star-forming regions to directly detect exoplanets over an unexplored range of masses, ages and orbit…
The Dynamic, Chimeric Inner Disk of PDS 70
Eric Gaidos, Thanawuth Thanathibodee, Andrew Hoffman +4
Transition disks, with inner regions depleted in dust and gas, could represent later stages of protoplanetary disk evolution when newly-formed planets are emerging. The PDS 70 syst…
An Episode of Occultation Events in Gaia21bcv
Klaus W. Hodapp, Eric Gaidos, Matthew A. Kenworthy +4
A previously unremarkable star near the Canis Major OB1/R1 association underwent an episode of multiple deep brightness minima. Light curves based on archival Gaia, ZTF, NEOWISE da…
