Context: Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims: Considering the...
A novel black hole mass scaling relation based on coronal gas, and its dependence with the accretion disc
Using bona-fide black hole (BH) mass estimates from reverberation mapping and the line ratio [Si VI] 1.963$\rm{\mu m}$/Brγ broad as tracer of the AGN ionizing...
A novel framework for semi-Bayesian radial velocities through template matching
Context. The ability to detect and characterise an increasing variety of exoplanets has been made possible by the continuous development of stable, high...
A pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 characterized with CHEOPS
We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in the...
Context. The derivation of the effective temperature of a star is a critical first step in a detailed spectroscopic analysis. Spectroscopic methods suffer from...
A Photometric Diagnostic to Aid in the Identification of Transiting Extrasolar Planets
One of the obstacles in the search for exoplanets via transits is the large number of candidates that must be followed up, few of which ultimately prove to be...
Context. The sample of hot Jupiters that have been studied in great detail is still growing. In particular, when the planet transits its host star, it is...
A physically motivated definition for the size of galaxies in an era of ultradeep imaging
Present-day multiwavelength deep imaging surveys allow to characterize the outskirts of galaxies with unprecedented precision. Taking advantage of this...
A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54 ± 0.03 M ☉)...
