Direct Measurement of Polar Coronal Hole-like Solar Wind in its Acceleration Phase
Samuel T. Badman, Yeimy J. Rivera, Michael L. Stevens +38
The early evolution of fast polar coronal hole (PCH) solar wind remains largely unconstrained by in situ measurements. In March 2025, Parker Solar Probe (Parker) at its closest app…
Magneto-Archeology of White Dwarfs. Revisiting the fossil field scenario with observational constraints during the red giant branch
Lukas Einramhof, Lisa Bugnet, Leila Magdalena Calcaferro +2
The detection of strong, large-scale magnetic fields at the surface of only the oldest population of white dwarfs might point towards a hidden internal magnetic field slowly rising…
Unveiling complex magnetic field configurations in red giant stars
Srijan Bharati Das, Lukas Einramhof, Lisa Bugnet
Recent measurements of magnetic field strength inside the radiative interior of red giant stars open the way towards the characterization of the geometry of stable large-scale magn…
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…
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…
Recipe for inferring sub-surface solar magnetism via local mode-coupling using Slepian basis functions
Srijan Bharati Das
Direct seismic imaging of sub-surface flow, sound-speed and magnetic field is crucial for predicting flux tube emergence on the solar surface, an important ingredient for space wea…
Inferring solar differential rotation through normal-mode coupling using Bayesian statistics
Samarth G. Kashyap, Srijan Bharati Das, Shravan M. Hanasoge +2
Normal-mode helioseismic data analysis uses observed solar oscillation spectra to infer perturbations in the solar interior due to global and local-scale flows and structural asphe…
Sensitivity kernels for inferring Lorentz stresses from normal-mode frequency splittings in the Sun
Srijan Bharati Das, Tuneer Chakraborty, Shravan M. Hanasoge +1
Departures from standard spherically symmetric solar models, in the form of perturbations such as global and local-scale flows and structural asphericities, result in the splitting…
Modeling star-planet interactions in far-out planetary and exoplanetary systems
Srijan Bharati Das, Arnab Basak, Dibyendu Nandy +1
The outflowing magnetized wind from a host star shapes planetary and exoplanetary magnetospheres dictating the extent of its impact. We carry out three-dimensional (3D) compressibl…
Wavelet-Based Characterization of Small-Scale Solar Emission Features at Low Radio Frequencies
Akshay Suresh, Rohit Sharma, Divya Oberoi +36
Low radio frequency solar observations using the Murchison Widefield Array have recently revealed the presence of numerous weak, short-lived and narrow-band emission features, even…
