Abstract:
We present the results of our detailed spectroscopic and photometric
analysis of two previously unknown <1M☉ detached eclipsing
binaries: ASAS J045304-0700.4 and ASAS J082552-1622.8.
Description:
Photometric observations of two newly-discovered low-mass eclipsing
binaries: ASAS J045304-0700.4 (ASAS-04) and ASAS J082552-1622.8
(ASAS-08). V and I band curves were obtained in January 2008 with the
1.0-m Elizabeth telescope and its STE4 camera at the South African
Astronomical Observatory (SAAO).
