Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood

Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62

The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…

A sub-Earth-mass planet orbiting Barnard's star

J. I. Gonzalez Hernandez, A. Suarez Mascareno, A. M. Silva +37

Barnard's star is a primary target within the ESPRESSO guaranteed time observations (GTO) as it is the second closest neighbour to our Sun after the Centauri stellar system. We…

Mapping the exo-Neptunian landscape. A ridge between the desert and savanna

A. Castro-González, V. Bourrier, J. Lillo-Box +4

Atmospheric and dynamical processes are thought to play a major role in shaping the distribution of close-in exoplanets. A striking feature of such distribution is the Neptunian de…

TOI-5005 b: A super-Neptune in the savanna near the ridge

A. Castro-González, J. Lillo-Box, D. J. Armstrong +38

The Neptunian desert and savanna have recently been found to be separated by a ridge, an overdensity of planets in the period range of 3-5 days. These features are thought…

K2-399 b is not a planet. The Saturn that wandered through the Neptune desert is actually a hierarchical eclipsing binary

J. Lillo-Box, D. W. Latham, K. A. Collins +19

The transit technique has been very efficient in detecting planet candidate signals over the past decades. The so-called statistical validation approach has become a popular way of…

Unveiling the internal structure and formation history of the three planets transiting HIP 29442 (TOI-469) with CHEOPS

J. A. Egger, H. P. Osborn, D. Kubyshkina +91

Multiplanetary systems spanning the radius valley are ideal testing grounds for exploring the proposed explanations for the observed bimodality in the radius distribution of close-…

ExoplANETS-A: A VO database for host stars and planetary systems: The effect of XUV on planet atmospheres

M. Morales-Calderón, S. R. G. Joyce, J. P. Pye +12

ExoplANETS-A is an EU Horizon-2020 project with the primary objective of establishing new knowledge on exoplanet atmospheres. Intimately related to this topic is the study of the h…

The AstraLux-TESS high-spatial resolution imaging survey. Search for stellar companions of 215 planet candidates from TESS

J. Lillo-Box, M. Morales-Calderón, D. Barrado +6

Chance-aligned sources or blended companions can cause false positives in planetary transit detections or simply bias the determination of the candidate properties. In the era of h…

TESS and ESPRESSO discover a super-Earth and a mini-Neptune orbiting the K-dwarf TOI-238

A. Suárez Mascareño, V. M. Passegger, J. I. González Hernández +53

The number of super-Earth and mini-Neptune planet discoveries has increased significantly in the last two decades thanks to transit and radial velocity surveys. When it is possible…

Signs of magnetic star-planet interactions in HD 118203. TESS detects stellar variability that matches the orbital period of a close-in eccentric Jupiter-sized companion

A. Castro-González, J. Lillo-Box, A. C. M. Correia +4

Planetary systems with close-in giant planets can experience magnetic star-planet interactions that modify the activity levels of their host stars. The induced activity is known to…
