The ultracool dwarf DENIS-P J104814.7-395606. Chromospheres and coronae at the low-mass end of the main-sequence
B. Stelzer, J. Alcala, K. Biazzo +8
We have obtained an XMM-Newton observation and a broad-band spectrum from the ultraviolet to the near infrared with X-Shooter for one of the nearest M9 dwarfs, DENIS-P J1048-3956 (…
X-ray view of IC348 in the light of an updated cluster census
B. Stelzer, T. Preibisch, F. Alexander +4
We study the properties of the coronae of the low-mass stars in the young (~2-3Myr), nearby (~310pc) open cluster IC348 combining X-ray and optical/infrared data. The four existing…
Characterising the magnetic fields of the Herbig Ae/Be stars HD97048, HD150193, HD176386, and MWC480
S. Hubrig, M. Schoeller, I. Ilyin +6
Our knowledge of the presence and the role of magnetic fields in intermediate-mass pre-main-sequence stars remains very poor. We present the magnetic properties of four Herbig Ae/B…
Search of X-ray emission from roAp stars: The case of gamma Equulei
B. Stelzer, C. A. Hummel, M. Schöller +2
The detection of X-ray emission from Ap stars can be an indicator for the presence of magnetic activity and dynamo action, provided different origins for the emission, such as wind…
