Revisiting the atmosphere of HAT-P-70b with CARMENES high-resolution transmission spectroscopy

Tianjun Gan, Jaume Orell-Miquel, Fei Yan +19

Owing to hot and inflated envelopes that facilitate atmospheric studies, ultra-hot Jupiters (UHJs) have attracted much attention. Significant progress has been achieved, from enlar…

Evidence of Water Vapor in the Atmosphere of a Metal-Rich Hot Saturn with High-Resolution Transmission Spectroscopy

Sayyed A. Rafi, Stevanus K. Nugroho, Motohide Tamura +2

Transmission spectroscopy presents one of the most successful approaches for investigating the atmospheres of exoplanets. We analyzed the near-infrared high-resolution transmission…

A multi-wavelength look at the GJ 9827 system -- No evidence of extended atmospheres in GJ 9827 b and d from HST and CARMENES data

Ilaria Carleo, Allison Youngblood, Seth Redfield +18

GJ9827 is a bright star hosting a planetary system with three transiting planets. As a multi-planet system with planets that sprawl within the boundaries of the radius gap between…

VLT/CRIRES+ observations of warm Neptune WASP-107 b: Challenges in detecting molecules with ground-based transmission spectroscopy of cooler and cloudy exoplanets

Linn Boldt-Christmas, Adam D. Rains, Nikolai Piskunov +15

Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefi…

The Transit Ingress and the Tilted Orbit of the Extraordinarily Eccentric Exoplanet HD 80606b

Joshua N. Winn, Andrew W. Howard, John Asher Johnson +18

We present the results of a transcontinental campaign to observe the 2009 June 5 transit of the exoplanet HD 80606b. We report the first detection of the transit ingress, revealing…

Solar center-to-limb variation in Rossiter-McLaughlin and exoplanet transmission spectroscopy

Ansgar Reiners, Fei Yan, Momo Ellwarth +2

Line profiles from spatially unresolved stellar observations consist of a superposition of local line profiles that result from observing the stellar atmosphere under specific view…
