Variability and a vanishing YSO in the Serpens cloud core.

HORROBIN M.J., CASALI M.M. and EIROA C.

Abstract (from CDS):

This letter compares data from a recent near-IR study of the Serpens cloud core with data from previously published studies. It is found that one object, irs 81 has completely vanished, fading by more than 3.8 magnitudes at K, while a total of 10 of the observed objects have varied by over 0.5 magnitudes in H or K, with little change in colour. We have also discovered 13 new objects in the cloud core which were below the magnitude limit of previous studies.
