A study of the kinematic and volumetric co-evolution of Earth-directed CMEs

Ashutosh Pattnaik, Nat Gopalswamy, Ranadeep Sarkar +3

While flare-associated CMEs generally show a strong association between flare X-ray flux and CME kinematics, their volumetric evolution and its link to both kinematics and flare ac…

Unusual Circumstances of the 2024 June 8 GLE

Nat Gopalswamy, Pertti Makela, Hong Xie +3

Ground Level Enhancement (GLE) in large solar energetic particle (SEP) events is indicative of protons accelerated to GeV energies. Almost all GLE events are associated with sustai…

Role of CME clusters and CME-CME interactions in producing sustained -ray emission

Atul Mohan, Pertti Makela, Natchimuthuk Gopalswamy +2

Fast (V>1000) coronal mass ejections (CMEs) capable of accelerating protons beyond 300MeV are thought to trigger hours-long sustained -ray emiss…

Novel scaling laws to derive spatially resolved flare and CME parameters from sun-as-a-star observables

Atul Mohan, Natchimuthuk Gopalswamy, Hemapriya Raju +1

Coronal mass ejections (CMEs) are often associated with X-ray (SXR) flares powered by magnetic reconnection in the low-corona, while the CME shocks in the upper corona and interpla…

A catalog of multi-vantage point observations of type-II bursts: Statistics and correlations

Atul Mohan, Nat Gopalswamy, Hemapriya Raju +1

Coronal mass ejection (CME) often produces a soft X-ray (SXR) flare associated with the low-coronal reconnection and a type-II radio burst associated with an interplanetary (IP) CM…
