No Convincing Evidence for Tidal Binary Clusters in the Galaxy
Juan Casado, Zahra Al
Context. The existence of tidal binary clusters (TBCs) in the Milky Way has been repeatedly suggested using Gaia DR3 astrometry and recent catalogs of binary clusters and groups. H…
Dynamical Evolution of The Open Clusters Collinder 110 and NGC 2477
Zahra Al, Yüksel Karataş, Forough Rajaei
Using Gaia DR3 photometric and astrometric data, we identified the likely members of the open clusters Collinder 110 and NGC 2477, and derived their astrophysical and dynamical par…
Morphokinematic structure of the Planetary Nebula NGC 6563
Zahra Al, Federico Soto-Badilla, Yüksel Karataş +2
We present a morphokinematic analysis based on high-resolution long-slit echelle spectroscopy of the \nii line and narrowband imaging. Position-velocity diagrams revea…
CCD () photometry of the open cluster NGC 6793 and its dynamical evolution
Zahra Al, Yüksel Karataş, Raul Michel Murillo +4
We present new astrophysical parameters for the open cluster NGC~6793 based on new CCD photometry. We derived a reddening of ~mag and a heavy…
