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…
Star-Planet Interactions: Observational Techniques and Methods
P. Figueira, H. Korhonen, A. Buccino +8
This chapter summarizes the techniques and methods used to study star-planet interaction (SPI) from the observational point of view. SPI can produce a wide range of observational s…
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…
Modelling magnetic star-planet interaction in the iconic M dwarfs Proxima Centauri, YZ Ceti and GJ 1151
Luis Peña-Moñino, Miguel Pérez-Torres
The unambiguous detection of magnetic star-planet interaction (SPI) via radio observations would provide a novel method for detecting exoplanets and probing their magnetic fields.…
Main-oval auroral emission from a T6 brown dwarf: observations, modeling, and astrometry
J. C. Guirado, J. B. Climent, J. D. Bergasa +3
From a series of 5 GHz VLBA radio observations taken over 1-yr span, we present the detection of compact highly-polarized radio emission from the T6 brown dwarf WISE J112254.72+255…
Searching for star-planet interactions in GJ 486 at radio wavelengths with the uGMRT
L. Peña-Moñino, M. Pérez-Torres, D. Kansabanik +14
We search for radio emission from star-planet interactions in the M-dwarf system GJ~486, which hosts an Earth-like planet. We observed the GJ~486 system with the upgraded Giant Met…
TOI-4438 b: a transiting mini-Neptune amenable to atmospheric characterization
E. Goffo, P. Chaturvedi, F. Murgas +47
We report the confirmation and mass determination of a mini-Neptune transiting the M3.5 V star TOI-4438 (G 182-34) every 7.44 days. A transit signal was detected with NASA's TESS s…
Wolf 327b: A new member of the pack of ultra-short-period super-Earths around M dwarfs
F. Murgas, E. Pallé, J. Orell-Miquel +52
Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small () ultra-short-period (…
Phenomenology and periodicity of radio emission from the stellar system AU Microscopii
Sanne Bloot, Joseph R. Callingham, Harish K. Vedantham +6
Stellar radio emission can measure a star's magnetic field strength and structure, plasma density and dynamics, and the stellar wind pressure impinging on exoplanet atmospheres. Ho…
Evidence for a radiation belt around a brown dwarf
J. B. Climent, J. C. Guirado, M. Pérez-Torres +2
Radio observations of ultracool dwarfs, objects comprising brown dwarfs and the very lowest mass stars, have mainly focused on analyzing their light-curve and spectral energy distr…
The CARMENES search for exoplanets around M dwarfs. A long-period planet around GJ 1151 measured with CARMENES and HARPS-N data
J. Blanco-Pozo, M. Perger, M. Damasso +37
Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet science. Recently, a tantalisi…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
Energetic nuclear transients in luminous and ultraluminous infrared galaxies
T. M. Reynolds, S. Mattila, E. Kankare +5
Energetic nuclear outbursts have been discovered in luminous and ultraluminous infrared galaxies (U/LIRGs) at unexpectedly high rates. To investigate this population of transients,…
