On the center-to-limb variations of the He I 10830 Å triplet
A. G. M. Pietrow, C. Kuckein, M. Verma +4
We present high-resolution spectroscopic observations of the quiet-Sun center-to-limb variations (CLV) of the He I triplet at 10830 Å and the nearby Si I 10827 Å line, observed wit…
Exploring coronal abundances of M dwarfs at moderate activity levels
J. J. Chebly, K. Poppenhäger, J. D. Alvarado-Gómez +1
Main sequence stars of spectral types F, G, and K with low to moderate activity levels exhibit a recognizable pattern known as the first ionization potential effect (FIP effect), w…
X-ray variability of the triplet star system LTT1445 and evaporation history of the exoplanets around its A component
S. Rukdee, J. Buchner, V. Burwitz +3
The high-energy environment of the host stars could be deleterious for their planets. It is crucial to ascertain this contextual information to fully characterize the atmospheres o…
Solar Hα excess during Solar Cycle 24 from full-disk filtergrams of the Chromospheric Telescope
A. Diercke, C. Kuckein, P. W. Cauley +4
The chromospheric H-alpha spectral line is a strong line in the spectrum of the Sun and other stars. In the stellar regime, this spectral line is already used as a powerful tracer…
