We lack a reliable scenario for the formation and evolution of stars and their planetary systems, involving key factors such as magnetic fields and turbulence...
During the OJ-94 campaign one monitored the blazar 3C 66A as a secondary target. Here the authors present the observed V-band light curve. This blazar was in...
During the international OJ-94 campaign we have also monitored blazar 3C 66A. Since fall 1993 we have collected over 500 V-band observations. This constitutes...
During the OJ-94 campaign for the blazar OJ 287 the authors have obtained the best ever observed optical light curve for any extragalactic object. They have...
LIGHTS is an ultra-deep imaging survey that is 10 years ahead of the science to be done with the Vera Rubin Observatory. In this talk, I will update the current...
The Limb Shift Effect and its Variation with the Solar Cycle
The radial velocity limb shift effect has been measured for the K I 7699 Å line using a resonant scattering spectrophotometer in the summer of 1982. On the...
The Lines are Not Fine: Measuring Vanadium Abundances in M dwarfs from Hyperfine-Split Lines
Cool star atmospheres present challenges to chemical abundance studies. To date, only a handful of elements have been quantified for a handful of M dwarfs. In...
LiteBIRD, the next-generation cosmic microwave background (CMB) experiment, aims for a launch in Japan's fiscal year 2032, marking a major advancement in the...
