Precise Mass, Orbital Motion, and Stellar Properties of the M-dwarf Binary LP 349−25AB
The Astrophysical JournalLP 349−25 is a well-studied close stellar binary system comprised of two late M dwarf stars, where both stars are close to the limit between star and brown dwarf. This system was previously identified as a source of gigahertz radio emission.

The nearby population of M dwarfs with WISE: A search for warm circumstellar dust
, 2012 Circumstellar debris disks are important because of their connection to planetary systems. An efficient way to identify these systems is through their infrared excess.

The theoretical instability strip of M dwarf stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 The overstability of the fundamental radial mode in M dwarf models was theoretically predicted by Rodr guez-L pez et al. (2012). The periods were found to be in the ranges ~25-40 min and ~4-8 h, depending on stellar age and excitation mechanism. We have extended our initial M dwarf model grid in mass, metallicity, and mixing length parameter. We have

The mass of dwarf spheroidal galaxies and the missing satellite problem
, 2005 We present the results from a suite of N-body simulations of the tidal stripping of two-component dwarf galaxies comprising some stars and dark matter. We show that recent kinematic data from the local group dwarf spheroidal (dSph) galaxies suggests that

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution
Advanced Science, EarlyView.Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Lucky Imaging survey for southern M dwarf binaries
, 2010 While M dwarfs are the most abundant stars in the Milky Way, there is still large uncertainty about their basic physical properties (mass, luminosity, radius, etc.) as well as their formation environment. Precise knowledge of multiplicity characteristics
