Hungry Giants: WISE Excesses and Lithium Study (HG-WELS)

We have assembled a set of 316 targets thought to be K giants, two thirds of which are thought to be Li-rich, in order to test the association between IR excesses and lithium abundances. The targets come from the dlR97 study (biased toward IR-bright sources), the C12 study (assembled with limited biases to test correlations of various stellar parameters), and a wide variety of literature identifying Li-rich K giants. For these targets, we assembled a multiwavelength catalog spanning optical through 100 um data, using SDSS, NOMAD, 2MASS, DENIS, WISE, IRAS, AKARI, MSX, and Spitzer data.
