High-energy gamma-rays from stellar associations [PDF]
The Astrophysical Journal, 2003 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.

Stellar Associations in the LMC [PDF]
Symposium - International Astronomical Union, 1999 The stellar associations are defined as loose unbound concentrations of young stars with a bright OB stellar component, mainly located at the most recent star forming regions, representing the smallest units in the hierarchy of stellar systems in galaxies.

On the origin of stellar associations [PDF]
, 2020 In this review I discuss different theories of the formation of OB associations in the Milky Way, and provide the observational evidences in support of them. In fact, the second release of Gaia astrometric data (April 2018) is revolutionising the field, because it allows us to unravel the 3D structure and kinematics of stellar associations with ...

Stellar Associations and Regions of Star Formation [PDF]
Symposium - International Astronomical Union, 1987 The genetic nature of the OB and T-Tau stars connection with stellar associations is at present beyond any doubt. They present the characteristic population of the latter. From this important observational fact follows that all young objects connected with OB and T-Tau stars also originated in stellar associations, and hence, are genetically connected ...

Lithium Depletion of Nearby Young Stellar Associations [PDF]
The Astrophysical Journal, 2008 We estimate cluster ages from lithium depletion in five pre-main-sequence groups found within 100 pc of the Sun: TW Hydrae Association, Eta Chamaeleontis Cluster, Beta Pictoris Moving Group, Tucanae-Horologium Association and AB Doradus Moving Group.

Starspots and Undetected Binary Stars Have Distinct Signatures in Young Stellar Associations [PDF]
The Astrophysical JournalYoung stars form in associations, meaning that young stellar associations provide an ideal environment to measure the age of a nominally coeval population.

A Census of Chemically Peculiar Stars in Stellar Associations [PDF]
AstronomyThe pre-main-sequence evolution of the chemically peculiar (CP) stars on the upper main sequence is still a vast mystery and not well understood. Our analysis of young associations and open clusters aims to find (very) young CP stars to try to put a ...

Evolution of Stellar Clusters and Associations
, 1971 Star clusters are usually defined as agglomerations of stars in space, whose average projected densities appear to exceed the density of background stars. Cluster members are identified either by parallax measurements or by common motion or also with the help of the color-luminosity diagram established from known members.
