Spatial and dynamical structure of the NGC 2264 star-forming region
E. Flaccomio, G. Micela, G. Peres +7
The processes that lead from molecular clouds to protostars, stellar associations, and the evolution of both, are active research topics. The target of this study, NGC2264, is a be…
TOI-179: a young system with a transiting compact Neptune-mass planet and a low-mass companion in outer orbit
S. Desidera, M. Damasso, R. Gratton +29
Transiting planets around young stars are key benchmarks for our understanding of planetary systems. One of such candidates was identified around the K dwarf HD 18599 by TESS, labe…
X-ray flares of the young planet host DS Tuc A
I. Pillitteri, C. Argiroffi, A. Maggio +5
Abridged. We observed the 40 Myr old star DS Tuc A with XMM-Newton and recorded two X-ray bright flares, with the second event occurring about 12 ks after the first one. Their dura…
Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
X-rays in Cepheids: Identifying Low-Mass Companions of Intermediate-Mass Stars
Nancy Remage Evans, Scott Engle, Ignazio Pillitteri +12
X-ray observations have been made of a sample of 20 classical Cepheids, including two new observations (Polaris and {\it l} Car) reported here. The occurrence of X-ray flux around…
X-ray variability of HD 189733 across eight years of XMM-Newton observations
I. Pillitteri, G. Micela, A. Maggio +2
The characterization of exoplanets, their formation, evolution, and chemical changes is tightly linked to our knowledge of their host stars. In particular, stellar X-rays and UV em…
