Program: GN-2011A-Q-9

We propose to use Gemini telescope and the GNIRS instrument, in order study a very low mass binary system (19g_4_02069). The host star of the system is a M4V red dwarf, discovered by the WTS (WFCAM Transit Survey) infrared survey. Using Gemini telescope and GNIRS, the expected accuracy is high enough to extract the spectroscopic lines of the secondary companion and therefore we will calculate the masses of both components. Our target is one of the lowest mass eclipsing binaries known. Gemini telescope and GNIRS is an ideal combination for successful observations and results.
