Using a new spectral disentangling approach to ascertain whether the massive binary HDE 228766 contains a Wolf-Rayet star

Edwin A Quintero, Philippe Eenens

The massive binary HDE 228766 is composed of an O type primary and an evolved secondary. However, previous qualitative analyses of the composite spectrum have led to a wide discuss…

The Massive Binary System 9 Sgr Revisited: New Insights into Disentangling Methods

Edwin A. Quintero, Philippe Eenens, Gregor Rauw

Disentangling techniques are often needed to obtain the spectra of the individual components of binary or multiple systems. A thorough analysis of the shift-and-add algorithm of Ma…

Time series of optical spectra of Nova V659 Sct

Dennis Jack, Klaus-Peter Schröder, Philippe Eenens +4

With our robotic 1.2 m TIGRE telescope, we were able to obtain eight optical spectra with intermediate resolution (R = 20,000) of the Nova V659 Sct during different phases of its o…

Study of the variability of Nova V5668 Sgr, based on high resolution spectroscopic monitoring

D. Jack, J. de J. Robles Pérez, I. De Gennaro Aquino +9

We present results of our dense spectroscopic monitoring of Nova V5668 Sgr. Starting on March 19 in 2015, only a few days after discovery, we have obtained a series of spectra with…

Simultaneous X-ray and optical spectroscopy of the Oef supergiant lambda Cep

G. Rauw, A. Herve, Y. Naze +8

Probing the structures of stellar winds is of prime importance for the understanding of massive stars. Based on their optical spectral morphology and variability, the stars of the…
