| Abstract: |
We report the discovery of 56 M-dwarf eclipsing binary candidates in
multi-band sparsely sampled time-series data collected by the Sloan Digital
Sky Survey (SDSS) over a period of ten years in SDSS Stripe 82. We briefly
describe the methods used to build a light-curve catalog of ∼ 1.4 million
point sources and identify ∼ 17,000 variable objects. Further, we discuss
the extraction and characterization of ∼ 600 periodic variables including
nearly 300 eclipsing binaries, including many examples of low mass K and
M-dwarf binaries. Finally, we describe our efforts to obtain preliminary
measurements of the relative luminosities, temperatures, and radii of the
stars in some of these binary systems by fitting models to their SDSS r and
i band light-curves. |
