Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

We present the results of the Gould's Belt Distances Survey of young star-forming regions
toward the Orion Molecular Cloud Complex. We detected 36 young stellar objects (YSOs) …

Most stars form and spend their early life in regions of enhanced stellar density. Therefore,
the evolution of protoplanetary discs (PPDs) hosted by such stars are subject to the …

We present the first installment of a massive spectroscopic survey of Galactic O stars, based
on new, high signal-to-noise ratio, R∼ 2500 digital observations from both hemispheres …

Context. Massive stars are a key element for understanding the chemical and dynamical
evolution of galaxies. Stellar evolution is conditioned by many factors: Rotation, mass loss …

Massive stars inject mechanical and radiative energy into the surrounding environment,
which stirs it up, heats the gas, produces cloud and intercloud phases in the interstellar …

Young stars are surrounded by a circumstellar disk of gas and dust, within which planet
formation can occur. Gravitational forces in multiple star systems can disrupt the disk …

Building on results from the Magnetism in Massive Stars (MiMeS) project, this paper shows
how a two-parameter classification of massive-star magnetospheres in terms of the magnetic …

Context. The Orion Molecular Cloud is the nearest massive-star forming region. Massive
stars have profound effects on their environment due to their strong radiation fields and …

The mass-luminosity (ML), mass-radius (MR) and mass-effective temperature ($ M-T_ {eff} $)
diagrams for a subset of galactic nearby main-sequence stars with masses and radii …
