The Kinematics of 30 Milky Way Globular Clusters and the Multiple Stellar Populations within

Ellen Leitinger, Holger Baumgardt, Ivan Cabrera-Ziri +5

The spectroscopic and photometric classification of multiple stellar populations (MPs) in Galactic globular clusters (GCs) has enabled comparisons between contemporary observations…

Kinematic differences between multiple populations in Galactic globular clusters

Sven Martens, Sebastian Kamann, Stefan Dreizler +7

The formation process of multiple populations in globular clusters is still up for debate. Kinematic differences between the populations are particularly interesting in this respec…

Hazy with a chance of star spots: constraining the atmosphere of the young planet, K2-33b

Pa Chia Thao, Andrew W. Mann, Peter Gao +10

Although all-sky surveys have led to the discovery of dozens of young planets, little is known about their atmospheres. Here, we present multi-wavelength transit data for the super…

pyobs -- An observatory control system forrobotic telescopes

Tim-Oliver Husser, Frederic V. Hessman, Sven Martens +3

We present a Python-based framework for the complete operation of a robotic telescope observatory. It provides out-of-the-box support for many popular camera types while other hard…

An Isolated Stellar-Mass Black Hole Detected Through Astrometric Microlensing

Kailash C. Sahu, Jay Anderson, Stefano Casertano +90

We report the first unambiguous detection and mass measurement of an isolated stellar-mass black hole (BH). We used the Hubble Space Telescope (HST) to carry out precise astrometry…
