Binaries as Tracers of Stellar Formation [Paperback]

This 1992 book discusses observations on binary stars with the aim of disentangling evidence of stellar formation from later physical evolution.Binary stars are considered as one of the best constraints on stellar formation models. Observations on multiple stellar systems are discussed in these proceedings, first published in 1992, with the aim of disentangling evidence of stellar formation from later physical evolution.Binary stars are considered as one of the best constraints on stellar formation models. Observations on multiple stellar systems are discussed in these proceedings, first published in 1992, with the aim of disentangling evidence of stellar formation from later physical evolution.More than two-thirds of all stars belong to multiple-star systems. Observation of binary stars is considered one of the best methods to test stellar formation models. This book presents the most recent observations of binaries with the aim of disentangling evidence of stellar formation from later physical evolution.1.
