Yet another star in the Albireo system -- The discovery of Albireo Ad
D. Jack, K. -P. Schröder, M. Mittag +1
Context. Albireo is a well-known bright visual double star. It is still unclear if the components A and B form a gravitationally bound system. The component Albireo A is itself a b…
Bright Spectroscopic Binaries: II. A study of five systems with orbital periods of P < 500 days
Dennis Jack, Missael Alejandro Hernández Huerta, Faiber Danilo Rosas-Portilla +1
We present a detailed analysis of five bright spectroscopic binary systems (HD 18665, HD 27131, HD 171852, HD 215550, HD 217427) that have orbital periods of P < 500 days. We deter…
Connecting the formation of stars and planets. II: coupling the angular momentum of stars with the angular momentum of planets
L. M. Flor-Torres, R. Coziol, K. -P. Schröder +2
A sample of 46 stars, host of exoplanets, is used to search for a connection between their formation process and the formation of the planets rotating around them. Separating our s…
Connecting the formation of stars and planets. I -- Spectroscopic characterization of host stars with TIGRE
L. M. Flor-Torres, R. Coziol, K. -P. Schröder +3
In search for a connection between the formation of stars and the formation of planets, a new semi-automatic spectral analysis method using \textsf{iSpec} was developed for the TIG…
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…
