Evidence of Truly Young High-α Dwarf Stars

Evidence of Truly Young High-α Dwarf Stars

The existence of high- α stars with inferred ages <6 Gyr has been confirmed recently with large spectroscopic and photometric surveys. However, stellar mergers or binary interactions can induce properties associated with young ages, such as high mass, rapid rotation, or high activity, even in old...
