The theory of radiatively-driven winds successfully explains the key points of the stellar winds of hot massive stars. However, it has been recently found that...
Massive Stars: Some Open Questions and the Role of Multi-Object Spectroscopy
Massive stars are key ingredients in the evolution of the Universe. Yet, important uncertainties and limits persist in our understanding of these objects, even...
Massive stellar systems: observational challenges and perspectives in the E-ELT era
We introduce the empirical framework concerning optical and near-infrared (NIR) photometry of crowded stellar fields. In particular, we address the impact that...
The MASTER auto-detection system at Tunka (Baykal Lake) detected a new transient source at the position (R.A., Dec) = 16h 39m 42.75s, +12d 24m 14s.4, (J2000)...
MASTER Follow-up Observations of LIGO GW170104 Event
We present the results of MASTER Global Robotic Net optical observations of the LIGO GW170104 error-box during the LIGO/Virgo O2 run. We observed 3421 square...
MASTER Optical Observation of LIGO/VIRGO S200224ca Error-box
We present the results of MASTER Global Robotic Net optical observations of LIGO/Virgo S200224ca error-box (O3 set). We observed 380 square degrees inside the...
