Thousands of RR Lyrae stars have been observed by the Kepler space telescope so far. We developed a photometric pipeline tailored to the light variations of...
K2 Warm Jupiters with the LCOGT TECH collaboration
Many transiting gas giant planets on short orbital periods (so called hot Jupiters) have larger radii than theoretically expected. Although several explanations...
Many if not most transiting gas giant planets on short orbital periods (so called hot Jupiters) have larger radii than theoretically expected. Although several...
Keck Spectroscopy of Z ~ 3 Galaxies in the Hubble Deep Field
We have obtained spectra with the 10-m Keck telescope of a sample of 24 galaxies having colors consistent with star-forming galaxies at redshifts 2 ≲ z ≲ 4.5 in...
Kelvin-Helmholtz and Rayleigh-Taylor instabilities in partially ionised prominences
We study the modification of the classical criterion for the linear onset and growing rate of the Kelvin-Helmholtz Instability (KHI) and the Rayleigh-Taylor...
Kepler meets Gaia: Binary systems, color-magnitude diagram, and kinematic analysis
The Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields including Galactic studies...
