Modelling the Center-to-Limb systematic in normal-mode-coupling measurements
Samarth G. Kashyap, Shravan M. Hanasoge
Solar meridional circulation, which manifests as poleward flow near the surface, is a relatively weak flow. While meridional circulation has been measured through various local hel…
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…
Probing Depth Variations of Solar Inertial Modes through Normal Mode Coupling
Krishnendu Mandal, Shravan M. Hanasoge
Recently discovered inertial waves, observed on the solar surface, likely extend to the deeper layers of the Sun. Utilizing helioseismic techniques, we explore these motions, allow…
Magnetic flux in the Sun emerges unaffected by supergranular-scale surface flows
Prasad Mani, Chris S. Hanson, Siddarth Dhanpal +3
Magnetic flux emergence from the convection zone into the photosphere and beyond is a critical component of the behaviour of large-scale solar magnetism. Flux rarely emerges amid f…
