On Infrared Excesses Associated With Li-Rich K Giants [PDF]

open access: yes, 2015
Infrared (IR) excesses around K-type red giants (RGs) have previously been discovered using IRAS data, and past studies have suggested a link between RGs with overabundant Li and IR excesses, implying the ejection of circumstellar shells or disks.
