A celestial matryoshka: Dynamical and spectroscopic analysis of the Albireo system
Ronald Drimmel, Alessandro Sozzetti, Klaus-Peter Schroeder +4
We present a spectroscopic characterisation and a new orbital solution for the binary system beta Cyg Aa/Ac (MCA 55), the primary component (beta Cyg A) of the well-known wide doub…
Bright Spectroscopic Binaries: I. Orbital parameters of five systems with periods of P < 365 days
Dennis Jack, Missael Alejandro Hernández Huerta, Klaus-Peter Schröder
In a well-aimed search based on the recently published Gaia~DR2 radial velocity data and performed with the robotic TIGRE telescope, we have discovered 19 bright (~mag) s…
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…
