Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares

Kosuke Namekata, Vladimir S. Airapetian, Pascal Petit +14

Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass eject…

SPIRou reveals unusually strong magnetic fields of slowly rotating M dwarfs

L. T. Lehmann, J. -F. Donati, P. Fouque +8

In this paper, we study six slowly rotating mid-to-late M~dwarfs (rotation period ) by analysing spectropolarimetric data collected wi…

Evolution of helium triplet transits of close-in gas giants orbiting K-dwarfs

Andrew P. Allan, Aline A. Vidotto, Carolina Villarreal D'Angelo +2

Atmospheric escape in exoplanets has traditionally been observed using hydrogen Lyman- and H- transmission spectroscopy, but more recent detections have utilised the metastab…

The space weather around the exoplanet GJ 436 b. II. Stellar wind-exoplanet interactions

A. A. Vidotto, V. Bourrier, R. Fares +5

The M dwarf star GJ 436 hosts a warm-Neptune that is losing substantial amount of atmosphere, which is then shaped by the interactions with the wind of the host star. The stellar w…

Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis

Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31

The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…

CUTE reveals escaping metals in the upper atmosphere of the ultra-hot Jupiter WASP-189b

A. G. Sreejith, Kevin France, Luca Fossati +12

Ultraviolet observations of Ultra-hot Jupiters (UHJs), exoplanets with temperatures over 2000\,K, provide us with an opportunity to investigate if and how atmospheric escape shapes…
