C. E. Ferreira Lopes, N. J. G. Cross, M. Catelan +17
Thanks to the VISTA Variables in the Via Lactea (VVV) ESO Public Survey it is now possible to explore a large number of objects in those regions. This paper addresses the variabili…
Faint Standards for ZYJHK from the UKIDSS and VISTA Surveys
S. K. Leggett, Nicholas J. G. Cross, Nigel C. Hambly
The currently defined "UKIRT Faint Standards" have JHK magnitudes between 10 and 15, with K_median=11.2. These stars will be too bright for the next generation of large telescopes.…
