Complete analysis of the subgiant stellar system: HIP 102029
Mardini, Mohammad K.; Al-Wardat, Mashhoor A.; Abu-Alrob, Enas M. +2 more
In this work, we present a detailed analysis of the individual components of the visual binary system HIP 102029 (R.A. = 20:40:35.32, Dec. = +15:38:35.63). The system was discovered during the European Space Agency Hipparcos mission and has a separation of 220 mas. The analysis uses the ORBITX code and Al-Wardat's method to estimate the orbital, a…
Discovered a new open cluster near the poorly studied Majaess 190
Tadross, A. L.
We present the results of a comprehensive astrophysical study of a newly discovered open cluster, dubbed Ash-1. Using the third data release of the Gaia space mission, Gaia DR3, Ash-1 was accidentally discovered within the constellation Sagittarius in the field of the poorly studied cluster Majaess 190. Here we present the first estimates of these…
The 24 Aqr triple system: A closer look at its unique high-eccentricity hierarchical architecture
Horch, Elliott P.; Abushattal, Ahmad A.; Al-Wardat, Mashhoor A. +4 more
As its periastron passage occurred during the third quarter of 2020, system 24 Aqr is of particular significance. New visual solutions for the latest speckle interferometry observations collected by the Lowell Discovery Telescope (LTD) with its new QWSSI speckle camera are presented here. A variety of techniques were used to analyze the system, in…
Some observational properties of the Herbig Be Star AS 310
Bakış, Volkan; Alishov, S. A.; Ismailov, Nariman Z. +2 more
The results of spectral and photometric studies of Herbig Be-type star AS 310 have been presented. Photometric observations in the BVRcIc bands performed in 2016-2021 showed that the amplitude of the seasonal brightness variations of the star changes smoothly in different years and reaches a maximum of approximately around Δ V ∼ 0.6 mag in 2018.
