Carrington cycle 24: The solar chromospheric emission in a historical and stellar perspective
K. -P. Schroder, M. Mittag, J. H. M. M. Schmitt +3
We present the solar S-index record of cycle 24, obtained by the TIGRE robotic telescope facility and its high-resolution spectrograph HEROS (R20,000), which measures the…
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…
Time series of high resolution spectra of SN 2014J observed with the TIGRE telescope
D. Jack, M. Mittag, K. -P. Schroder +6
We present a time series of high resolution spectra of the Type Ia supernova 2014J, which exploded in the nearby galaxy M82. The spectra were obtained with the HEROS echelle spectr…
Identification of the feature that causes the I-band secondary maximum of a type Ia supernova
D. Jack, E. Baron, P. H. Hauschildt
We obtained a time series of spectra covering the secondary maximum in the I-band of the bright Type Ia supernova 2014J in M82 with the TIGRE telescope. Comparing the observations…
A 3D radiative transfer framework IX. Time dependence
D. Jack, P. H. Hauschildt, E. Baron
Context. Time-dependent, 3D radiation transfer calculations are important for the modeling of a variety of objects, from supernovae and novae to simulations of stellar variability…
Theoretical light curves of type Ia supernovae
D. Jack, P. H. Hauschildt, E. Baron
Aims. We present the first theoretical SN Ia light curves calculated with the time-dependent version of the general purpose model atmosphere code PHOENIX. Our goal is to produce li…
