The Orion OB1 stellar association is a contingent group of several dozen hot giant stars of spectral types O and B. Associated are thousands of lower-mass stars, and a (smaller but significant) number of protostars. It is part of the larger Orion Molecular Cloud Complex. Owing to its relative closeness and complexity it is the most closely studied OB association. [1]
"OB Associations play an important role in the large scale propagation of star formation and in the shaping and evolution of the interstellar medium". [1]
The Orion OB1 association consists of the following subgoups: [1] [2]
Signatures of stellar debris disk evolution have been detected in the 1a and 1b subgroups. [7] [8]
