  • Study of lithium and other related elements among evolved stars 
    Mallick, Anohita (Indian Institute of Astrophysics, 2025-01)
    The formation and evolution of elements is a fundamental problem in modern astrophysics. Lithium (Li), one of the four stable nuclides produced during Big Bang Nucleosynthesis (BBN), exhibits an observed abundance in many ...
  • Stromgren photometric metallicity map of the magellanic cloud stars using Gaia DR3–XP spectra 
    Omkumar, Abinaya O; Cioni, Maria-Rosa L; Subramanian, S; de Bruijne, Jos; Nair, Aparna; Dias, Bruno (EDP Sciences, 2025-08)
    Context. One key to understanding a galaxy’s evolution is studying the consequences of its past dynamical interactions that have influenced its shape. By measuring the metallicity distribution of stellar populations with ...
  • Constraining the nature and long-term stability of FRB 20121102A’s persistent radio source 
    Bhardwaj, Mohit; Balasubramanian, Arvind; Kaushal, Yasha; Tendulkar, Shriharsh (IOP Publishing, 2025-08)
    The persistent radio source (PRS) associated with FRB 20121102A, the first precisely localized repeating fast radio burst (FRB), provides key constraints on both its local environment and the nature of the underlying ...
  • The relation between solar spicules and magnetohydrodynamic shocks 
    Srivastava, Sankalp; Chatterjee, Piyali; Dey, Sahel; Erdelyi, Robertus (American Astronomical Society, 2025-08-10)
    Spicules are thin, elongated, jet-like features seen in observations of the solar atmosphere, at the interface between the solar photosphere and the corona. These features exhibit highly complex dynamics and are a necessary ...
  • Photospheric helium abundance in cool giants: a comprehensive study 
    Hema, B. P; Pandey, G (American Astronomical Society, 2025-08-20)
    High-resolution optical spectra of 16 red giants, two early asymptotic giant branch (AGB) stars, and two supergiants, having no/minimal - to super-lithium (Li)-rich abundances, are analyzed to investigate the helium ...
