An optical absorption study of the Helix Planetary Nebula: NaI and CaII lines, and a search for diffuse bands
N. Mauron, T. R. Kendall
We present the results of an optical absorption study of NGC 7293, the Helix planetary nebula (PN), designed to search for diffuse band (DIB) absorptions perhaps arising in the car…
Low-mass substellar candidates in NGC 2264
Tim Kendall, Jerome Bouvier, Estelle Moraux +1
NGC 2264 is a young (3 Myr), populous star forming region for which our optical studies have revealed a very high density of potential brown dwarf (BD) candidates - 236 in less tha…
Discovery of very nearby ultracool dwarfs from DENIS
T. R. Kendall, X. Delfosse, E. L. Martin +1
We report new spectroscopic results, obtained with UKIRT/CGS4, of a sample of 14 candidate ultracool dwarfs selected from the DENIS (Deep Near-Infrared Survey of the Southern Sky)…
Cool carbon stars in the halo: a new survey based on 2MASS
N. Mauron, M. Azzopardi, K. Gigoyan +1
We present the first results of a new survey for finding cool N-type carbon (C) stars in the halo of the Galaxy. Candidates were first selected in the 2MASS Second Incremental Rele…
