The cargo and transportation sector is growing day by day. Resources need to be managed more efficiently in the face of growth fast delivery demand customer requests. Location selection branches route planning processes vehicles are important order manage resources efficiently. Geographic Information Systems (GIS) provide significant advantages site processes. Especially open source GIS data so...

We investigate the three open clusters near Aquila Rift cloud, named as UPK 39 (\texttt{c1} hereafter), 41 (\texttt{c2} hereafter) in Sim et al. (2019) and PHOC (\texttt{c3} Hunt \& Reffert (2021), respectively. Using photometric passpands, reddening, extinction from Gaia DR3, we construct color-absolute-magnitude diagram (CAMD). isochrone fits their ages are estimated $6.3\pm0.9$, $8.1\pm1.4$ ...

ABSTRACT We report the discovery of an ultrafaint dwarf in constellation Pegasus. Pegasus V (Peg V)/Andromeda XXXIV was initially identified public imaging data release DESI Legacy Imaging Surveys and confirmed with deep from Gemini/GMOS-N. The colour–magnitude diagram shows a sparse red giant branch (RGB) population strong overdensity blue horizontal stars. measure distance to Peg $D=692^{+33}...

Our aim is to derive a self-consistent age, distance and composition for the globular cluster 47 Tucanae (47 Tuc; NGC104). First, we reevaluate the reddening towards the cluster resulting in a nominal E(B − V) = 0.03 ± 0.01 as the best estimate. The Teff of the components of the eclipsing binary member V69 is found to be 5900± 72 K from both photometric and spectroscopic evidence. This yields a...

Abstract We report 541 new open-cluster candidates in Gaia EDR3 through revisiting the cluster results from an earlier analysis of DR2, which revealed nearly 1000 solar neighborhood (mostly d <3 kpc) residing at Galactic latitudes ∣ b < 20°. A subsequent comparison with lists known clusters shows a large increase samples within 2 kpc Sun. assign membership probabilities to stars open-sour...

ABSTRACT The Tucana-Horologium association is one of the closest young stellar groups to Sun and despite close proximity its age still debated in literature. We take advantage state-of-the-art astrometry delivered by third data release Gaia space mission combined with precise radial velocity measurements obtained from high-resolution spectroscopy investigate dynamical association. perform an ex...

Abstract We present a new method to assess the properties of transiting planet candidates by multicolor photometry. By analyzing transit/eclipse light curves and apparent magnitudes target in parallel, this attempts identify nature system provide quantitative constraint on unresolved companion(s). demonstrate our observing six systems hosting candidate planets, identified K2 mission (EPIC 20603...

We present a photometric and kinematical analysis of two poorly studied open clusters, Koposov 12 (FSR 802) 43 848), by using cross-matched data from PPMXL Gaia DR2 catalogs. used astrometric parameters to identify 285 310 cluster members for 43, respectively. Using the extracted member candidates isochrone fitting near-infrared (J, H, Ks) bands (G, GBP, GRP), color-magnitude diagrams (CMDs), w...
