Galactic Clusters and Stellar Associations
2014A casual glance at the night sky may lead you into believing that stars are solitary, isolated objects, but in fact no star is born in isolation. As we have discussed in previous chapters, the process of star birth takes place in immense interstellar clouds of dust and gas that, depending upon the cloud’s size, can give rise to anything from a few ...

Relationship between pulsars and stellar associations
Astrophysics, 1997The spatial distribution of pulsars and stellar associations in the solar neighborhood is investigated on the basis of recent data. The distribution of young pulsars and stellar associations indicates fragments of the spiral structure of the galaxy.

The Stellar Content of the Orion OB1 Association
Space Science Reviews, 1994We 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

Observations of stellar magnetism and associated phenomena
EAS Publications Series, 2013This paper first surveys how stellar magnetic fields are measured, and especially the impact of the most recent spectropolarimeters on our measurement capabilities. The two main types of stellar magnetism, dynamo and fossil fields, are discussed in a general way. This is followed by a broad survey of the current level of knowledge of magnetic fields in

Stellar associations in the galaxy NGC 2403
Publications of the Astronomical Society of the Pacific, 1985Stellar associations in the Sc galaxy NGC 2403 are identified and compared to similar samples in Local Group galaxies. Their properties, including the total number delineated, their sizes, the average number of supergiant stars they contain, and their radial distribution are tabulated and are shown to be similar to those of M33 and the LMC. The stellar

Stellar Content and Evolution of OB Associations
Publications of the Astronomical Society of the Pacific, 1996An important goal in astronomy is to understand the star formation process. Studies thereof have led to fairly detailed theoretical knowledge of the formation of individual stars. However, there is no detailed understanding of the origin of global properties of the stellar population, such as the initial mass function.
