The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

An Efficient Method for Measuring the Color of a Natural Satellite with Astrometric Applications
The Astronomical JournalThe Gaia DR3 catalog released in 2022 contains precise broadband photometry for more than one billion stars in the G , BP, and RP passbands, which is very useful for calibrating the differential color refraction (DCR) effect in ground-based observations.

Commission 24: Photographic Astrometry: (Astrometrie Photographique) [PDF]
Transactions of the International Astronomical Union, 2000 The scope of scientific interests of about 130 Commission members is much more complex than one may expect from the title of the commission. Besides traditional topics like the compilation of astrometric catalogues and the construction of an inertial reference system, more and more investigations performed by our members have been dedicated to the ...

Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT We present new radial velocity measurements of 13 selected intermediate mass stars (2–6 M⊙). The measurements were performed between 29 April and 6 September 2024 at the University Observatory Jena using the échelle spectrograph FLECHAS. The radial velocity of eight stars was found to be constant during our spectroscopic monitoring, namely: 17

Discovery of Hundreds of Main-belt Asteroids with Synthetic Tracking of WISE Data
The Planetary Science JournalWe analyze 1.5 million W3 Wide-field Infrared Survey Explorer (WISE) images acquired between 2010 January 7 and 2010 August 6 with the SALTAD synthetic tracking package to report astrometry of previously known and unknown main belt asteroids. We consider

Commission 8: Astrometry [PDF]
Proceedings of the International Astronomical Union, 2005 AbstractThis triennial report from Commission 8 covers astrometry-related matters for objects ranging from Solar system bodies out to Milky Way stars and QSOs at cosmological distances. This enormous range of distances is needed to establish, maintain, and improve the metric of the visible Universe--a very challenging effort since everything is moving.

Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Advances in Astronomy, Volume 2026, Issue 1, 2026.The continued detection of near‐Earth asteroids with postulated close encounters with Earth is a clear motivation for planetary defense–driven mission designs. Fast reconnaissance in an imminent threat scenario (i.e., less than a few years upon impact) is crucial to gain information about an asteroid potentially impacting the Earth in the near future ...
