Isotopes of titanium in Aldebaran.
Abstract
The titanium isotopic abundance ratios in the K5 giant Aldebaran (Alpha Tau) are estimated from photoelectric high-resolution (40 mA) scans of portions of the TiO gamma-system (0, 0) band between 7070 and 7082 A. An application of spectrum synthesis techniques shows that the overall Ti isotopic abundance ratio is terrestrial to within 50%, with individual ratios terrestrial to within 25%. The (1, 0) and (0, 1) gamma-system band heads are reviewed as potential isotopic abundance indicators in late M stars.
