Precise Physical Parameters, Habitability, and Orbital Stability of Sun-like SB2 Systems: HD 130669, HD 184467, HD 191854, and HD 214222
This work analyzes four Sun-like double-lined spectroscopic binary (SB2) systems by combining visual and spectroscopic observational data with Al-Wardat’s atmospheric modeling method to accurately determine their fundamental parameters.

Stellar Flares In The TESS Light Curves Of Planet-hosting M dwarfs
M dwarfs are magnetically active stars that frequently produce flares, which have implications for both stellar evolution and exoplanet studies.
