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 …

ABSTRACT HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright (G= 9.0 mag) solar
analogue. TESS photometry revealed the star to have two candidate planets with radii of …

Context. Multi-planet systems are important sources of information regarding the evolution of
planets. However, the long-period planets in these systems often escape detection. These …

The metastable helium triplet in the near-infrared (10 833 Å) is among the most important
probes of exoplanet atmospheres. It can trace their extended outer layers and constrain …

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 …

Context. Understanding planet formation is important in the context of the origin of planetary
systems in general and of the Solar System in particular, as well as to predict the likelihood …

Planets that closely orbit magnetically active stars are thought to be able to interact with their
magnetic fields in a way that modulates stellar activity. This modulation in phase with the …

The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues
about the early dynamical history of planetary systems. Here, we present the first …

Active comets have been detected in several exoplanetary systems, although so far only
indirectly, when the dust or gas in the extended coma has transited in front of the stellar disk …

AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing
variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar …
