OB stellar associations in the Large Magellanic Cloud: Survey of young stellar systems [PDF]

Astronomy and Astrophysics, 2003
The method developed by Gouliermis et al. (2000, Paper I), for the detection and classification of stellar systems in the LMC, was used for the identification of stellar associations and open clusters in the central area of the LMC.

Dynamical models of stellar associations

Astronomical and Astrophysical Transactions, 1998
Abstract Numerical N-body investigations of the dynamical evolution of a young stellar aggregate embedded in a massive interstellar cloud are presented. We discuss some mechanisms of the formation of OB-associations – traditional as well as new ones.

High-Energy Gamma Rays from Stellar Associations [PDF]

Astrophysical Journal, 2004
It is proposed that TeV gamma-rays and neutrinos can be produced by cosmic rays (CRs) through hadronic interactions in the innermost parts of the winds of massive O and B stars. Convection prevents low-energy particles from penetrating into the wind, leading to an absence of MeV-GeV counterparts.

Polarimetric Investigations of Stellar Associations

Astrophysics, 2002
The degree of polarization of light from stars in 44 O B associations as a function of interstellar absorption is investigated. It is shown that the character of the dependence of P on AV for stars in associations and stars not in associations depends on the value of AV: for AV ≤ 2m.5 it has a linear character and is the same for both groups of stars ...

Formation of stellar associations

Astrophysics and Space Science, 1970
The Rayleigh-Taylor instability forms massive complexes. When 1021 atoms cm−2 are gathered, X-rays which heat the gas and UV-rays which ionize carbon are absorbed. A layer should appear with temperatures as low as 6 K and density to 4×103 cm−3. Finally the layer is fragmented into stars whose masses may even be less than one solar mass. The temperature

The Stellar Content of the Orion OB1 Association

Space Science Reviews, 1994
We present a photometric investigation, using the VBLUW system, of the stellar content of Orion OB1. Physical parameters (logg;, logT eff) for the stars are derived with the aid of model atmospheres. From these, visual extinctions, absolute magnitudes and distance moduli are derived. The distance moduli are used to determine membership for the stars in
