Report

Detection of wide binary and multiple nuclei of planetary nebulae using the Gaia DR3

Autor: Ali, A., Khalil, J. M., Mindil, A.

Context: this paper describes the detection of wide binary and multiple central stars (CSs) of Galactic planetary nebulae (PNe) using the most up-to-date data available from the Gaia Data Release 3 (Gaia DR3). Aims: the objective of this study is to

Report

The variability and radial velocity of planetary nebulae central stars

Autor: Ali, A., Mindil, A.

The extremely accurate estimates of stellar variability and radial velocity in the Gaia Data Release 3 (Gaia DR3) have enabled us to examine the close binarity and radial velocity (RV) of central stars (CSs) of planetary nebulae (PNe). This study is

Interacting planetary nebulae III: Verification and galactic population based on the measurements of Gaia EDR3

Autor: Mohery, M., Ali, A., Mindil, A., Alghamdi, S. A

The phenomenon of interaction between planetary nebulae (PNe) and the interstellar medium (ISM) is one of the significant issues in the field of astrophysics. The main objective of this paper is to verify the interaction process for objects that have

Report

A new statistical distance scale for planetary nebulae, based on Gaia EDR3

Autor: Ali, A., Algarni, E., Mindil, A., Alghamdi, S. A.

The present work aims to build a new statistical distance scale for planetary nebulae (PNe) based on a rigorous calibration sample. The distances of the calibration sample are derived from the trigonometric parallax method using the recent measuremen
