Optical atmospheric extinction over Cerro Paranal
F. Patat, S. Moehler, K. O'Brien +14
Aims: The present study was conducted to determine the optical extinction curve for Cerro Paranal under typical clear-sky observing conditions, with an accuracy of 0.01 mag/airmass…
High-angular resolution observations of the Pistol Star
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
First results of near-IR adaptive optics (AO)-assisted imaging, interferometry, and spectroscopy of this Luminous Blue Variable (LBV) are presented. They suggest that the Pistol St…
The multiplicity of massive stars
H. Sana, C. J. Evans
Binaries are excellent astrophysical laboratories that provide us with direct measurements of fundamental stellar parameters. Compared to single isolated star, multiplicity induces…
A MAD view of Trumpler 14
H. Sana, Y. Momany, M. Gieles +5
We present adaptive optics (AO) near-infrared observations of the core of the Tr 14 cluster in the Carina region obtained with the ESO multi-conjugate AO demonstrator, MAD. Our cam…
