In this paper we review the current situation regarding the study of the metallicity-giant planet connection. We show that planet-host stars are more metal-rich...
The exoplanet satellite hunter CHEOPS of the European Space Agency (ESA), in which the Instituto de Astrofísica de Canarias (IAC) is participating along with...
Company for the Ultra-high Density, Ultra-short Period Sub-Earth GJ 367 b: Discovery of Two Additional Low-mass Planets at 11.5 and 34 Days
GJ 367 is a bright (V ≈ 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of...
Concepts for future missions to search for technosignatures
New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet...
Among the over 450 known exoplanets, the planets that transit their central star stand out, due to the wealth of information that can be gained about both...
Correcting Exoplanet Transmission Spectra for Stellar Activity with an Optimized Retrieval Framework
The chromatic contamination that arises from photospheric heterogeneities, e.g., spots and faculae on the host star presents a significant noise source for...
Descubren el exoplaneta potencialmente habitable más cercano a la Tierra
Una investigación internacional, en la que participa el Instituto de Astrofísica de Canarias (IAC), ha hallado un planeta de tamaño intermedio entre la Tierra y...
Detailed Chemical Abundances for a Benchmark Sample of M Dwarfs from the APOGEE Survey
Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high...
Detection of Ionized Calcium in the Atmosphere of the Ultra-hot Jupiter KELT-9b
With a dayside temperature in excess of 4500 K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a...
