The Gaia-ESO Survey: Target selection of open cluster stars
A. Bragaglia, E. Alfaro, E. Flaccomio +36
The Gaia-ESO Survey (GES) is a public, high-resolution spectroscopic survey with FLAMES@VLT. GES targeted in particular a large sample of open clusters (OCs) of all ages. The diffe…
The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
Cronomoons: origin, dynamics, and light-curve features of ringed exomoons
Mario Sucerquia, Jaime A. Alvarado-Montes, Amelia Bayo +8
In recent years, technical and theoretical work to detect moons and rings around exoplanets has been attempted. The small mass/size ratios between moons and planets means this is v…
Observational constraints and dynamical analysis of Kaniadakis horizon-entropy cosmology
A. Hernández-Almada, Genly Leon, Juan Magaña +5
We study the scenario of Kanadiakis horizon entropy cosmology which arises from the application of the gravity-thermodynamics conjecture using the Kaniadakis modified entropy. The…
Minimax properties of Dirichlet kernel density estimators
Karine Bertin, Christian Genest, Nicolas Klutchnikoff +1
This paper considers the asymptotic behavior in -Hölder spaces, and under losses, of a Dirichlet kernel density estimator proposed by Aitchison and Lauder (1985) for the a…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with {\it TESS}: III. Asteroseismology of the DBV star GD 358
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +14
The collection of high-quality photometric data by space telescopes is revolutionizing the area of white-dwarf asteroseismology. Among the different kinds of pulsating white dwarfs…
