Abstract:
We develop a method to identify the spectroscopic signature of
unresolved L-dwarf ultracool companions, which compares the spectra of
candidates and their associated control stars using spectral ratio
differences and residual spectra. We present SpeX prism-mode spectra
(0.7-2.5 micron) for a pilot sample of one hundred and eleven mid M
dwarfs, including twenty-eight which were previously identified as
candidates for unresolved ultracool companionship (a sub-sample from
Cook et al. 2016; paper 1) and eighty-three single M dwarfs which were
optically colour-similar to these candidates (which we use as `control
stars'). We identify four candidates with evidence for near-infrared
excess. One of these (WISE J100202.50+074136.3) shows strong evidence
for an unresolved L dwarf companion in both its spectral ratio
difference and its residual spectra, two most likely have a different
source for the near-infrared excess, and the other may be due to
spectral noise. We also establish expectations for a null result (i.e.
by searching for companionship signatures around the M dwarf control
stars), as well as determining the expected outcome for ubiquitous
companionship (as a means of comparison with our actual results),
using artificially generated unresolved M+L dwarf spectra. The results
of these analyses are compared to those for the candidate sample, and
reasonable consistency is found. With a full follow-up program of our
candidates sample from paper 1, we might expect to confirm up to 40
such companions in the future, adding extensively to the known desert
population of M3-M5 dwarfs.
Description:
NCJM is the catalogue created for finding unresolved UCD companions to
M dwarfs. The full catalogue comprises of a cross-match between
WISE/SDSS/2MASS and subsequent cross-matches between PPMXL and
reddening data from Schlafly and Finkneiner 2011ApJ...737..103S 2011ApJ...737..103S and
Schlegel et al. (1998ApJ...500..525S 1998ApJ...500..525S). This catalogue was then
cross-matched against LAMOST dr1 (Cat. V/146) and dr2 (Cat. V/149),
and compared to West et al. (2011, Cat. J/AJ/141/97). The M dwarfs
were selected using colour cuts (J-H and H-KS) colour constraints
from Lepine & Gaidos (2011, Cat. J/AJ/142/138) as well as basic
photometry and accuracy cuts (see Cook et al., 2016MNRAS.457.2192).
The Strict cuts catalogue is a sub-sample of the full catalogue. It
contains the cuts included as columns in this table (including
Reddening, accuracy and photometric cuts), and those sources from the
main catalogue can be identified by the Strictcutselection column in
the full catalogue. The M+UCD candidates were selected using colour
excess in J-W2 (columns ex_jw2 for details see Cook et al.,
2016MNRAS.457.2192). These were selected from the strict cut catalogue
(where improvement was greater than four times random selection, see
column ExcesscandImp_4.0 in NJCMstrictcuts.fits).
