Eight years of TIGRE robotic spectroscopy: Operational experience and selected scientific results
J. N. González-Perez, M. Mittag, J. H. M. M. Schmitt +4
TIGRE (Telescopio Internacional de Guanajuato Robótico Espectroscópico) has been operating in fully robotic mode in the Observatory La Luz (Guanajuato, Mexico) since the end of 201…
A highly mutually-inclined, compact warm-Jupiter system KOI-984 ?
Leilei Sun, Panagiotis Ioannidis, Shenghong Gu +6
The discovery of a population of close-orbiting giant planets ( 1 au) has raised a number of questions about their origins and dynamical histories. These issues have still not…
Orbital obliquity sampling in the Kepler-20 system using the 3D animation software Blender
Holger M. Müller, Panagiotis Ioannidis, Jürgen H. M. M. Schmitt
The mutual orbital alignment in multiple planetary systems is an important parameter for understanding their formation. There are a number of elaborate techniques to determine the…
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…
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…
