Many if not most transiting gas giant planets on short orbital periods (so called hot Jupiters) have larger radii than theoretically expected. Although several...
K<SUB>s</SUB>-band Photometry of the Extreme T Subdwarf CWISE J221706.28‑145437.6
We present deep K s-band imaging of the extreme T subdwarf CWISE J221706.28‑145437.6. Using the new photometry, we construct its spectral energy distribution...
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...
Kepler observations: Light shed on the hybrid γ Doradus - δ Scuti pulsation phenomenon
Through the observational study of stellar pulsations, the internal structure of stars can be probed and theoretical models can be tested. The main sequence γ...
