Evidence for TiO in the Atmosphere of the Hot Jupiter HAT-P-65 b
We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 M Jup, 1.89 R Jup, T eq = 1930 K), based on two transits observed...
Gliese 12 b: A Temperate Earth-sized Planet at 12 pc Ideal for Atmospheric Transmission Spectroscopy
Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up...
Heaviest element yet detected in an exoplanet atmosphere
An international team of astronomers, in which IAC researchers participate, have discovered barium, the heaviest element ever found in an exoplanet atmosphere...
High-resolution Emission Spectroscopy of the Ultrahot Jupiter KELT-9b: Little Variation in Day- and Nightside Emission Line Contrasts
The transmission spectrum of the ultrahot Jupiter KELT-9b (T eq ~ 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular...
High-resolution Spectroscopic Reconnaissance of a Temperate Sub-Neptune
The study of temperate sub-Neptunes is the new frontier in exoplanetary science. A major development in the past year has been the first detection of carbon...
Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass
K2-136 is a late-K dwarf (0.742 ± 0.039 M ⊙) in the Hyades open cluster with three known, transiting planets and an age of 650 ± 70 Myr. Analyzing K2 photometry...
Identification of the Top TESS Objects of Interest for Atmospheric Characterization of Transiting Exoplanets with JWST
JWST has ushered in an era of unprecedented ability to characterize exoplanetary atmospheres. While there are over 5000 confirmed planets, more than 4000...
MARK MARLEY: “One great challenge when studying planetary atmospheres is clouds, which both brown dwarfs and extrasolar planets have”
Our planet becomes too small for some scientists, therefore they dedicate their lives to study other worlds much larger than Earth and those that are so massive...
