Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres
F. Nail, M. MacLeod, A. Oklopčić +3
Recent observations of planetary atmospheres in HAT-P-32 b and HAT-P-67 b reveal extensive outflows reaching up to hundreds of planetary radii. The helium 1083 nm light curves for…
Water absorption in the transmission spectrum of the water-world candidate GJ9827d
Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +16
Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than often host H…
A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation
Michael Gully-Santiago, Caroline V. Morley, Jessica Luna +14
Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present t…
Giant Tidal Tails of Helium Escaping the Hot Jupiter HAT-P-32 b
Zhoujian Zhang, Caroline V. Morley, Michael Gully-Santiago +14
Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. Such analysis has been enabled by observations of the helium…
The unusual M-dwarf Warm Jupiter TOI-1899~b: Refinement of orbital and planetary parameters
Andrea S. J. Lin, Jessica E. Libby-Roberts, Jaime A. Alvarado-Montes +31
TOI-1899 b is a rare exoplanet, a temperate Warm Jupiter orbiting an M-dwarf, first discovered by Cañas et al. (2020) from a TESS single-transit event. Using new radial velocities…
H-alpha and Ca II Infrared Triplet Variations During a Transit of the 23 Myr Planet V1298 Tau c
Adina D. Feinstein, Benjamin T. Montet, Marshall C. Johnson +5
Young transiting exoplanets (< 100 Myr) provide crucial insight into atmospheric evolution via photoevaporation. However, transmission spectroscopy measurements to determine atmosp…
The Featureless HST/WFC3 Transmission Spectrum of the Rocky Exoplanet GJ 1132b: No Evidence For A Cloud-Free Primordial Atmosphere and Constraints on Starspot Contamination
Jessica E. Libby-Roberts, Zachory K. Berta-Thompson, Hannah Diamond-Lowe +10
Orbiting a M dwarf 12 pc away, the transiting exoplanet GJ 1132b is a prime target for transmission spectroscopy. With a mass of 1.7 Earth masses and radius of 1.1 Earth radii, GJ…
The Young Planet DS Tuc Ab has a Low Obliquity
Benjamin T. Montet, Adina D. Feinstein, Rodrigo Luger +9
The abundance of short-period planetary systems with high orbital obliquities relative to the spin of their host stars is often taken as evidence that scattering processes play imp…
The Ring Structure in the MWC 480 Disk Revealed by ALMA
Yao Liu, Giovanni Dipierro, Enrico Ragusa +20
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this paper, we present and analyze high resolution (0.17*0.11 arcsec) 1.3 mm ALMA c…
Understanding Stellar Contamination in Exoplanet Transmission Spectra as an Essential Step in Small Planet Characterization
Dániel Apai, Benjamin V. Rackham, Mark S. Giampapa +18
Transmission spectroscopy during planetary transits is expected to be a major source of information on the atmospheres of small (approximately Earth-sized) exoplanets in the next t…
The Architecture of the GW Ori Young Triple Star System and Its Disk: Dynamical Masses, Mutual Inclinations, and Recurrent Eclipses
Ian Czekala, Sean M. Andrews, Guillermo Torres +15
We present spatially and spectrally resolved Atacama Large Millimeter/submillimeter Array (ALMA) observations of gas and dust orbiting the pre-main sequence hierarchical triple sta…
