Intense but Harmless: Exo-Space Weather Around an M Dwarf with a Single-Hemisphere Dynamo
Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian +4
M dwarfs are among the most promising host stars in the search for habitable exoplanets. However, their active atmospheres drive intense magnetic activity, including energetic flar…
The ORCA-TWIN qCMOS Experiment I. Science case and commissioning at Calar Alto Observatory
Martin M. Roth, Pasko Roje, Stella Vjesnica +18
We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. Th…
Numerical quantification of the wind properties of cool main sequence stars
Judy Chebly, Julián D. Alvarado-Gómez, Katja Poppenhäger +1
As a cool star evolves, it loses mass and angular momentum due to magnetized stellar winds which affect its rotational evolution. This change has consequences that range from the a…
Complete X-ray census of Mdwarfs in the solar Neighborhood I. GJ 745 AB: Coronal-hole Stars in the 10 pc Sample
M. Caramazza, B. Stelzer, E. Magaudda +4
We have embarked in a systematic study of the X-ray emission in a volume-limited sample of M dwarf stars, in order to explore the full range of activity levels present in their cor…
The high energy universe at ultra-high resolution: the power and promise of X-ray interferometry
Phil Uttley, Roland den Hartog, Cosimo Bambi +24
We propose the development of X-ray interferometry (XRI), to reveal the universe at high energies with ultra-high spatial resolution. With baselines which can be accommodated on a…
51 Pegasi - a planet-bearing Maunder minimum candidate
K. Poppenhaeger, J. Robrade, J. H. M. M. Schmitt +1
We observed 51 Peg, the first detected planet-bearing star, in a 55 ks XMM-Newton pointing and in 5 ks pointings each with Chandra HRC-I and ACIS-S. The star has a very low count r…
