Journal ArticleDOI
Absolute proper motions of open clusters - I. Observational data
TL;DR: Mean proper motions and parallaxes of 205 open clusters were determined from their member stars found in the Hipparcos Catalogue 360 clusters were searched for possible members, excluding nearby clusters with distances D < 200 pc.
Journal ArticleDOI
The locations of recent supernovae near the Sun from modelling 60 Fe transport
Dieter Breitschwerdt,Jenny Feige,M. M. Schulreich,M. A. de Avillez,C. Dettbarn,Burkhard Fuchs +5 more
TL;DR: Calculations of the most probable trajectories and masses of the supernova progenitors, and hence their explosion times and sites, are reported and the model reproduces the measured relative abundances very well.
Journal ArticleDOI
The search for the origin of the Local Bubble redivivus
Burkhard Fuchs,Dieter Breitschwerdt,M. A. de Avillez,M. A. de Avillez,C. Dettbarn,Chris Flynn +5 more
TL;DR: In this paper, an unbiased search and analysis of all B stars within a volume of 400 pc diameter using the Arivel data base to track down theremains of the OB associations, which hosted the supernovae responsible for the Local Bubble in the interstellar gas is presented.
Journal ArticleDOI
The kinematics of late type stars in the solar cylinder studied with SDSS data
B. Fuchs,C. Dettbarn,Hans-Walter Rix,Timothy C. Beers,D. Bizyaev,Howard Brewington,H. Jahreiss,Rainer J. Klement,E. Malanushenko,V. Malanushenko,D. Oravetz,Kaike Pan,A. Simmons,Stephanie A. Snedden +13 more
TL;DR: In this article, the velocity distribution of stars in a kiloparsec-sized region around the Sun is studied, based on 2 million M-type stars from DR7 of SDSS, which have newly re-calibrated absolute proper motions from combining positions with the USNO-B catalogue.

B. Fuchs,C. Dettbarn,Hans-Walter Rix,Timothy C. Beers,Dmitry Bizyaev,Howard Brewington,H. Jahreiß,Rainer J. Klement,Elena Malanushenko,Viktor Malanushenko,Daniel Oravetz,Kaike Pan,Audrey Simmons,Stephanie A. Snedden +13 more
TL;DR: In this paper, the velocity distribution of the stars in a kiloparsec-sized region around the Sun is studied, based on approximately 2 million M-type stars from DR7 of SDSS, which have newly re-calibrated absolute proper motions from combining positions with the USNO-B catalogue.
