Radio emission from star-planet interactions

H. K. Vedantham, A. Strugarek, C. K. Louis +12

Stars interact with their exoplanets though gravity, radiation, plasma and magnetic fields. Stellar plasma and magnetic fields impose electrodynamic effects on exoplanet atmosphere…

Constraining an exoplanets magnetic field using star-planet interactions

D. Revilla, P. J. Amado, R. Luque +17

Theory predicts that a planet with a sufficiently strong magnetic field orbiting close to its host star could induce star-planet magnetic interactions. This is potentially observab…

Orbital motion and dynamical mass of the complex periodic variable binary system 2MASS J05082729-2101444

S. Curiel, G. N. Ortiz-León, V. J. S. Béjar +22

We used very long baseline interferometry to constrain the orbit of the binary system 2MASS J05082729-2101444. We observed the system with the VLBA in three epochs at a frequency o…

Spinning out of focus: The challenge of rotational line broadening in exoplanet reflection spectroscopy

T. O. Winterhalder, K. Molaverdikhani, D. Cont +17

Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour. Despite several attempts, the fa…

A gem system with a lava world and a habitable zone sub-Neptune orbiting TOI-1752

A. Peláez-Torres, F. J. Pozuelos, G. Morello +47

The Transiting Exoplanet Survey Satellite (TESS) has delivered a large number of transiting planet candidates around nearby stars by identifying periodic decreases in stellar brigh…

The CARMENES search for exoplanets around M dwarfs. A homogeneous catalogue of projected rotational velocities accounting for limb-darkening

R. Varas, G. Morello, M. Zechmeister +18

Stellar rotation is closely linked to both age and magnetic activity. Through gyrochronology, it provides a means to estimate stellar ages and trace the evolution of planetary syst…
