Deformation and differential rotation in slowly rotating young intermediate-mass stars
S. K. Panda, S. Hanasoge
Asteroseismology, the study of stellar vibrations, is a method which can probe the structure deformation and internal rotation of stars. Salient among the seismic inferences of rot…
Seismic constraints on the spin evolution of slowly rotating young intermediate-mass stars
K. H. Singh, S. K. Panda, S. M. Hanasoge +1
Scuti stars are hot, rapid rotators and are a poorly understood class of pulsators. Asteroseismology provides the only means with which to probe their interior dynamics. Howeve…
Quadratic frequency dispersion in the oscillations of intermediate-mass stars
Subrata Kumar Panda, Shravan Hanasoge, Siddharth Dhanpal +1
Asteroseismology, the study of stellar vibration, has met with great success, shedding light on stellar interior structure, rotation, and magnetism. Prominently known as Scutis…
Detectability of axisymmetric magnetic fields from the core to the surface of oscillating post-main sequence stars
Shatanik Bhattacharya, Srijan Bharati Das, Lisa Bugnet +2
Magnetic fields in the stellar interiors are key candidates to explain observed core rotation rates inside solar-like stars along their evolution. Recently, asteroseismic estimates…
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…
