Results from the first spectropolarimetric survey of Dor pulsators

J. Labadie-Bartz, R. Ouazzani, C. Neiner +8

Context. Magnetic fields can have an important influence on stellar structure and evolution. In intermediate-mass (A- and F-type) stars, there are many known stars with directly me…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

Magnetohydrodynamic instabilities in stellar radiative regions. I. Linear study of shear-driven instabilities

V. Durepaire, L. Petitdemange, K. Belkacem +4

This paper is the first in a series investigating magnetohydrodynamic instabilities that may contribute to angular-momentum transport and magnetic-field evolution in stellar radiat…

Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle

I. Pillitteri, S. Bellotti, S. Benatti +7

High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…

Euclid Quick Data Release (Q1) Ultracool dwarfs in the Euclid Deep Field North

A. Mohandasan, R. L. Smart, C. Reylé +176

Ultracool dwarfs (UCDs) encompass the lowest mass stars and brown dwarfs, defining the stellar substellar boundary. They have significant potential for advancing the understanding…

Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data

M. Libralato, L. R. Bedin, M. Griggio +175

The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
