UBVRI night sky brightness at Kottamia Astronomical Observatory
Mohamed F. Aboushelib, Abdelfady B. Morcos, Samir Nawar +2
Photoelectric observations of night sky brightness (NSB) at different zenith distances and azimuths, covering all the sky, at the Egyptian Kottamia Astronomical observatory (KAO) s…
Physical and kinematical characteristics of Wolf-Rayet central stars and their host planetary nebulae
Zainab Awad, Alaa Ali
We addressed the physical and kinematical properties of Wolf -- Rayet [WR] central stars (CSs) and their hosting planetary nebulae (PNe). The studied sample comprises all [WR] CSs…
Interstellar Hydrocarbons: Degradation Chemistry in Diffuse Clouds
Zainab Awad, Serena Viti
Observations of diffuse clouds showed that they contain a number of simple hydrocarbons (e.g. CH, CH, (l- and c-)CH, and CH) in abundances that may be difficult to…
A comprehensive photometric and kinematical characteristic of the newly discovered QCs clusters with Gaia EDR3
W. H. Elsanhoury, Magdy Y. Amin, A. A. Haroon +1
This study reports the first comprehensive astrometric, photometric and kinematical analysis of four newly discovered open clusters; namely QC1, QC2, QC3, and QC4, using astrometri…
On the Formation of Deuterated Methyl Formate in Hot Corinos
Zainab Awad, Audrey Coutens, Serena Viti +1
Methyl formate, HCOOCH, and many of its isotopologues have been detected in astrophysical regions with considerable abundances. However, the recipe for the formation of this mo…
Gravitational interaction signatures in isolated galaxy triplet systems: a photometric analysis
Amira A. Tawfeek, Kanak Saha, Kaustubh Vaghmare +7
Galaxy triplets are interesting laboratories where we can study the formation and the evolution of small and large systems of galaxies. This study aims to investigate signs of inte…
