Disentangling broadening components in line-profiles of Galactic OB stars

27/05/2014

The IACOB spectroscopic database has allowed identifying a variety of different types of line-profiles present in the realm of the O and B-type stars. These line-profiles are broadened by rotation as well as other broadening components. A study performed by Simón-Díaz (SO Postdoc) & Herrero, researchers of the IAC and the University of La Laguna, has allowed extracting actual information about the stellar rotation from the line-profiles independently from the effect of other line-broadening mechanisms. >>Read more
