Using raytracing to derive the expected performance of STELLA's SES-VIS spectrograph
Michael Weber, Klaus Strassmeier, Manfred Woche +2
The visual STELLA echelle spectrograph (SES-VIS) is a new instrument for the STELLA-II telescope at the Izaña observatory on Tenerife. Together with the original SES spectrograph -…
Second generation spectroscopic instrumentation for the STELLA robotic observatory
Michael Weber, Manfred Woche, Klaus G. Strassmeier +2
The current STELLA Echelle spectrograph (SES), which records 390nm to 870nm in one shot at a spectral resolution of 55000, will be replaced by a suite of specialized spectrographs…
On the binary orbit of Henry Draper one (HD 1)
Klaus G. Strassmeier, Michael Weber
We present our final orbit for the late-type spectroscopic binary HD 1. Employed are 553 spectra from 13 years of observations with our robotic STELLA facility and its high-resolut…
Spatially Resolved Ultraviolet Spectroscopy of the Great Dimming of Betelgeuse
Andrea K. Dupree, Klaus G. Strassmeier, Lynn D. Matthews +9
The bright supergiant, Betelgeuse (Alpha Orionis, HD 39801) experienced a visual dimming during 2019 December and the first quarter of 2020 reaching an historic minimum 2020 Februa…
Spectangular: Disentangling variable spectra
Daniel P. Sablowski, Silva Järvinen, Michael Weber
Spectangular is a GUI based software package written in C++ designed for spectral disentangling on the wavelength scale. The code disentangles spectra of SB1 and SB2 systems and ca…
Contemporaneous Imaging Comparisons of the Spotted Giant Geminorum Using Interferometric, Spectroscopic, and Photometric Data
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +8
Nearby, active stars with relatively rapid rotation and large starspot structures offer the opportunity to compare interferometric, spectroscopic, and photometric imaging technique…
