The Sun and other stars are magnetic: magnetism pervades their interiors and affects their
evolution in a variety of ways. In the Sun, both the fields themselves and their influence on …

Partially ionized plasmas are found across the Universe in many different astrophysical
environments. They constitute an essential ingredient of the solar atmosphere, molecular …

This paper presents an overview of SPIRou, the new-generation near-infrared
spectropolarimeter/precision velocimeter recently installed on the 3.6-m Canada–France …

We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr
M1 star AU Microscopii (AU Mic) collected with the high-resolution YJHK (0.98–2.35 μm) …

In this paper, we present an analysis of near-infrared spectropolarimetric and velocimetric
data of the young M dwarf AU Mic, collected with SPIRou at the Canada–France–Hawaii …

We present near-infrared spectropolarimetric observations of a sample of 43 weakly to
moderately active M dwarfs, carried with SPIRou at the Canada–France–Hawaii Telescope …

We report results of a spectropolarimetric monitoring of the young Sun-like star V1298 Tau
based on data collected with the near-infrared spectropolarimeter SPIRou at the Canada …

Radio detections of stellar systems provide a window onto stellar magnetic activity and the
space weather conditions of extrasolar planets—information that is difficult to obtain at other …

Context. Over the last two decades, a large population of close-in planets has been detected
around a wide variety of host stars. Such exoplanets are likely to undergo planetary …

The aim of this study is to analyse the Earth habitability with respect to the direct exposition
of the Earth atmosphere to the solar wind (SW) along the Sun's evolution on the main …
