Discovery of metal-poor and distant pre-main sequence candidates in WLM with JWST
Venu M. Kalari, Ricardo Salinas, Morten Andersen +4
We present the discovery of twelve metal-poor and distant pre-main sequence (PMS) candidates in the dwarf irregular galaxy Wolf-Lundmark-Melotte (WLM)~968 kpc away, at a present-da…
A high-resolution imaging survey of massive young stellar objects in the Magellanic Clouds
Venu M. Kalari, Ricardo Salinas, Hans Zinnecker +3
Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs…
The Carina High-Contrast Imaging Project for massive Stars (CHIPS) I. Methodology and proof of concept on QZ Car ( HD93206)
A. Rainot, M. Reggiani, H. Sana +13
Massive stars like company. However, low-mass companions have remained extremely difficult to detect at angular separations () smaller than 1" (~1000-3000 au considering typical…
Sparse Aperture Masking of Massive Stars
H. Sana, S. Lacour, J. -B. Le Bouquin +5
We present the earliest results of our NACO/VLT sparse aperture masking (SAM) campaign to search for binarity in a sample of 60 O-type stars. We detect Delta Ks < 5 mag companions…
Star formation history of CMa R1: I. Wide-field X-ray study of the young stellar population
J. Gregorio-Hetem, T. Montmerle, C. V. Rodrigues +3
The CMa R1 star-forming region contains several compact clusters as well as many young early-B stars. It is associated with a well-known bright rimmed nebula, the nature of which i…
