Spectroscopic and Photometric Study of the new Scuti Star ASAS J063309+1810.8
Mohamed I. Nouh, Mohamed Abdel-Sabour, Ahmed Shokry +3
We present BVR observations and low-resolution spectra collected by the Kottamia Astronomical Observatory 1.88 m telescope (KAO) for the new pulsating star ASAS J063309+1810.8 (her…
Photometric and Spectroscopic Analysis of the SX Phe Star BL Cam
Mohamed Abdel-Sabour, Mohamed I. Nouh, Ahmed Shokry +5
In the present paper, we report the photometric and spectroscopic observations obtained by the 1.88 m telescope at the Kottamia astronomical observatory of the pulsating star BL Ca…
Fundamental parameters of some B-type stars using NOAO Indo-U.S. Library
A. Shokry, M. I. Nouh, S. M. Saad +1
In the present article, we present a spectroscopic analysis of 83 field B-type stars from NOAO Indo-U.S. Library. We calculated the fundamental parameters e.g effective temperature…
A Study of the Time Variability and Line Profile Variations of kappa Dra
S. M. Saad, M. I. Nouh, A. Shokry +1
In this study, we present a spectroscopic analysis of the bright Be star kappa Dra. Two independent sets of radial velocity velocities (RV) measurements were obtained by direct mea…
Breaking the dichotomy between typical and anomalous globular clusters: the case of NGC 3201
Bruno Dias, Ignacio Araya, João Paulo Nogueira-Cavalcante +2
We recently discovered that NGC 3201 has characteristics that set it outside the current twofold classification scheme for Galactic globular clusters (GCs). Most GCs are mono-metal…
Stellar parameters of Be stars observed with X-shooter
A. Shokry, Th. Rivinius, A. Mehner +10
Aims. The X-shooter archive of several thousand telluric star spectra was skimmed for Be and Be-shell stars to derive the stellar fundamental parameters and statistical properties,…
