Stellar Contamination Correction Using Back-to-Back Transits of TRAPPIST-1 b and c
Alexander D. Rathcke, Lars A. Buchhave, Julien De Wit +8
Stellar surface heterogeneities, such as spots and faculae, often contaminate exoplanet transit spectra, hindering precise atmospheric characterization. We demonstrate a novel, epo…
An extremely low-density exoplanet spins slow
Quanyi Liu, Wei Zhu, Kento Masuda +3
We present constraints on the shape of Kepler-51d, which is a super-puff with a mass and a radius , based on detailed modeling of the transit lig…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49
Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…
Redshifted Sodium Transient near Exoplanet Transit
Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21
Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…
JWST reveals a rapid and strong day side variability of 55 Cancri e
J. A. Patel, A. Brandeker, D. Kitzmann +16
The nature of the close-in rocky planet 55 Cnc e is puzzling despite having been observed extensively. Its optical and infrared occultation depths show temporal variability, in add…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
A secondary atmosphere on the rocky exoplanet 55 Cancri e
Renyu Hu, Aaron Bello-Arufe, Michael Zhang +14
Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the…
Constraints on atmospheric water abundance and cloud deck pressure in the warm Neptune GJ 3470 b via CARMENES transmission spectroscopy
Spandan Dash, Matteo Brogi, Siddharth Gandhi +4
Observations of cooler atmospheres of super-Earths and Neptune sized objects often show flat transmission spectra. The most likely cause of this trend is the presence of aerosols (…
LHS 1140 b is a potentially habitable water world
Mario Damiano, Aaron Bello-Arufe, Jeehyun Yang +1
LHS 1140 b is a small planet orbiting in the habitable zone of its M4.5V dwarf host. Recent mass and radius constraints have indicated that it has either a thick H-rich atmosph…
