Anomalously fast core and envelope rotation in red giants
Siddharth Dhanpal, Othman Benomar, Shravan Hanasoge +1
Red giants undergo dramatic and complex structural transformations as they evolve. Angular momentum is transported between the core and envelope during this epoch, a poorly underst…

Asteroseismology applied to constrain structure parameters of δ Scuti stars
Subrata Kumar Panda, Siddharth Dhanpal, Simon J. Murphy +2
Asteroseismology is a powerful tool to probe the structure of stars. Space-borne instruments like CoRoT, Kepler and TESS have observed the oscillations of numerous stars, among whi…

Inferring coupling strengths of mixed-mode oscillations in red-giant stars using deep learning
Siddharth Dhanpal, Othman Benomar, Shravan Hanasoge +3
Asteroseismology is a powerful tool that may be applied to shed light on stellar interiors and stellar evolution. Mixed modes, behaving as acoustic waves in the envelope and buoyan…
