Disentangled spectra of R145
Listed in IVOA Registry (Virtual Observatory)
We present the first SB2 orbital solution and disentanglement of the massive Wolf-Rayet binary R145 (P=159d) located in the Large Magellanic Cloud.
Description
The primary was claimed to have a stellar mass greater than 300M_{sun}_, making it a candidate for the most massive star known. While the primary is a known late type, H-rich Wolf-Rayet star (WN6h), the secondary could not be so far unambiguously detected.
Using moderate resolution spectra, we are able to derive accurate radial velocities for both components. By performing simultaneous orbital and polarimetric analyses, we derive the complete set of orbital parameters, including the inclination. The spectra are disentangled and spectroscopically analyzed, and an analysis of the wind-wind collision zone is conducted.
