COBRaS: The e-MERLIN 21 cm Legacy survey of Cygnus OB2
J. C. Morford, D. M. Fenech, R. K. Prinja +12
The role of massive stars is central to an understanding of galactic ecology. It is important to establish the details of how massive stars provide radiative, chemical, and mechani…
White paper for Chandra cool attitude targets (CAT): Stellar activity with TESS and Chandra
Hans Moritz Günther, David A. Principe, Carl Melis +9
All cool stars show magnetic activity, and X-ray emission is the hallmark of this activity. Gaining an understanding of activity aids us in answering fundamental questions about st…
X-ray spectral characterization of the young Cygnus OB2 population
E. Flaccomio, J. F. Albacete-Colombo, J. J. Drake +7
We analyze the X-ray spectra of the 8000 sources detected in the Cygnus OB2 Chandra Legacy Survey (Drake et al., this issue), with the goals of characterizing the coronal pla…
Photoevaporation and close encounters: how the environment around Cygnus OB2 affects the evolution of protoplanetary disks
M. G. Guarcello, J. J. Drake, N. J. Wright +10
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on t…
Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
L. Gkouvelis, J. Fabregat, J. Zorec +5
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotomet…
