Cool carbon stars in the halo: new very red or distant objects
N. Mauron, K. S. Gigoyan, T. R. Kendall
The goal of this paper is to present and analyse a new sample of cool carbon (C)stars located in the halo. Twenty three new C stars were discovered. Spectra are typical of N-type s…
New, nearby bright southern ultracool dwarfs
T. R. Kendall, H. R. A. Jones, D. J. Pinfield +5
We report the discovery of twenty-one hitherto unknown bright southern ultracool dwarfs with spectral types in the range M7 to L5.5, together with new observations of a further thr…
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…
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…
The envelope of IRC+10216 reflecting the galactic light: UBV surface brightness photometry and interpretation
N. Mauron, P. de Laverny, B. Lopez
We present and analyse new optical images of the dust envelope surrounding the high mass-loss carbon star IRC+10216. This envelope is seen due to external illumination by galactic…
Serendipitous discovery of seven new southern L-dwarfs
T. R. Kendall, N. Mauron, M. Azzopardi +1
We report the discovery of seven hitherto unknown L-dwarfs found as a result of a spectroscopic search for distant AGB stars. Their far-red and near-infrared colours are very simil…
