Abstract:
We present a detailed near-infrared/optical/UV study of the transient
low-mass X-ray binary 1RXS J180408.9-342058 performed during its 2015
outburst, which is aimed at determining the nature of its companion
star.
We obtained three optical spectra (R∼1000) at the 2.1m San Pedro
Martir Observatory telescope (Mexico). We performed optical and NIR
photometric observations with both the REM telescope and the New
Technology Telescope (NTT) in La Silla. We obtained optical and UV
observations from the Swift archive. Finally, we performed optical
polarimetry of the source using the EFOSC2 instrument mounted on the
NTT.
Description:
The system 1RXS J180408.9-342058 was observed on Apr. 20, 2015 with
the 2.1m telescope at the San Pedro Martir Observatory (Mexico),
equipped with the Boller & Chivens spectrograph. Three 1800s spectra
with a resolution of ∼6.5Å (350km/s) were acquired, covering the
wavelength range 4000-7800Å. The three spectra were combined and
averaged to obtain one final spectrum to increase the signal to noise
ratio (S/N).
