An ancient F-type subdwarf from the halo crossing the Galactic plane
R. -D. Scholz, U. Heber, C. Heuser +3
AIMS: We selected the bluest object, WISE~J07252351, from Luhman's new high proper motion (HPM) survey based on observations with the Wide-field Infrared Survey Explorer (WISE)…
The Hyper-MUCHFUSS project: probing the Galactic halo with sdB stars
A. Tillich, U. Heber, S. Geier +7
High-velocity stars in the Galactic halo, e.g. the so-called hyper-velocity stars (HVS), are important tracers of the properties of the dark matter halo, in particular its mass. Ba…
A halo blue straggler on a highly eccentric retrograde orbit
A. Tillich, N. Przybilla, R. -D. Scholz +1
Blue straggler, which are stars that appear to be younger than they should be, are an important population of unusual stars in both stellar clusters and the halo field of the Galax…
SDSS J013655.91+242546.0 - an A-type hyper-velocity star from the outskirts of the Galaxy
A. Tillich, N. Przybilla, R. -D. Scholz +1
Hyper-velocity stars (HVS) are moving so fast that they are unbound to the Galaxy. Dynamical ejection by a supermassive black hole is favoured to explain their origin. Locating the…
