Machine Learning-Based Characterization of Solar p-Mode Frequency Shifts during Solar Cycle 25
Rekha Jain, Akash Kumar, Sushanta C. Tripathy
The solar interior is probed by the properties of the Sun's acoustic oscillations (p-modes) observed on the solar surface. The frequencies of these p-modes measured in the last thr…
Overstable Convective Modes in a Polytropic Stellar Atmosphere
Bradley W. Hindman, Rekha Jain
Within the convection zone of a rotating star, the presence of the Coriolis force stabilizes long-wavelength convective modes. These modes, which would have been unstable if the st…
Study of transverse oscillations in coronal loops excited by flares and eruptions
Sandra M. Conde C, Rekha Jain, Vera Jatenco-Pereira
We present measurements of periodicity for transverse loop oscillations during the periods of activity of two remote and separated (both temporally and spatially) flares. The oscil…
Radial Trapping of Thermal Rossby Waves within the Convection Zones of Low-Mass Stars
Bradley W. Hindman, Rekha Jain
We explore how thermal Rossby waves propagate within the gravitationally stratified atmosphere of a low-mass star with an outer convective envelope. Under the conditions of slow, r…
Kink oscillations of coronal loops
V. M. Nakariakov, S. A. Anfinogentov, P. Antolin +13
Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy re…
Do Coronal Loops Oscillate in Isolation?
Bradley W. Hindman, Rekha Jain
Images of the solar corona by extreme-ultraviolet (EUV) telescopes reveal elegant arches of glowing plasma that trace the corona's magnetic field. Typically, these loops are prefer…
The need for new techniques to identify the high-frequency MHD waves of an oscillating coronal loop
Farhad Allian, Rekha Jain
Magnetic arcades in the solar atmosphere, or coronal loops, are common structures known to host magnetohydrodynamic (MHD) waves and oscillations. Of particular interest are the obs…
Critical Science Plan for the Daniel K. Inouye Solar Telescope (DKIST)
Mark P. Rast, Nazaret Bello González, Luis Bellot Rubio +84
The Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand and model the basic physical processes that control the structure and dynamics of…
A New Analysis Procedure for Detecting Periodicities within Complex Solar Coronal Arcades
Farhad Allian, Rekha Jain, B. W Hindman
We study intensity variations, as measured by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO), in a solar coronal arcade using a newly develope…
A Novel Approach to Resonant Absorption of the Fast MHD Eigenmodes of a Coronal Arcade
Bradley W. Hindman, Rekha Jain
The arched field lines forming coronal arcades are often observed to undulate as magnetohydrodynamic (MHD) waves propagate both across and along the magnetic field. These waves are…
Time-dependent suppression of oscillatory power in evolving solar magnetic fields
S. Krishna Prasad, D. B. Jess, R. Jain +1
Oscillation amplitudes are generally smaller within magnetically active regions like sunspots and plage, when compared to their surroundings. Such magnetic features, when viewed in…
Eigenmodes of three-dimensional magnetic arcades in the Sun's corona
Bradley W. Hindman, Rekha Jain
We develop a model of coronal-loop oscillations that treats the observed bright loops as an integral part of a larger 3-D magnetic structure comprised of the entire magnetic arcade…
Fundamental-Mode Oscillations of Two Coronal Loops within a Solar Magnetic Arcade
Rekha Jain, Ram A. Maurya, B. W. Hindman
We analyse intensity variations, as measured by the Atmospheric Imaging Assembly (AIA) in the 171 Å passband, in two coronal loops embedded within a single coronal magnetic arcade.…
Five-minute oscillation power within magnetic elements in the solar atmosphere
Rekha Jain, Andrew Gascoyne, Bradley W. Hindman +1
It has long been known that magnetic plage and sunspots are regions in which the power of acoustic waves is reduced within the photospheric layers. Recent observations now suggest…
An Interpretation of Flare-Induced and Decayless Coronal-Loop Oscillations as Interference Patterns
Bradley W. Hindman, Rekha Jain
We present an alternative model of coronal-loop oscillations which considers that the waves are trapped in a 2D waveguide formed by the entire arcade of field lines. This differs f…
Equilibrium models of coronal loops that involve curvature and buoyancy
Bradley W. Hindman, Rekha Jain
We construct magnetostatic models of coronal loops in which the thermodynamics of the loop is fully consistent with the shape and geometry of the loop. This is achieved by treating…
Kink Oscillations of a Curved, Gravitationally Stratified Coronal Loop
Bradley W. Hindman, Rekha Jain
Loops of magnetic field in the corona are observed to oscillate and these oscillations have been posited to be the superposition of resonant kink waves. To date, most analyses of t…
Axisymmetric Scattering of p Modes by Thin Magnetic Tubes
Bradley W. Hindman, Rekha Jain
We examine the scattering of acoustic p-mode waves from a thin magnetic fibril embedded in a gravitationally stratified atmosphere. The scattering is mediated through the excitatio…
Large Amplitude Oscillations in Prominences
D. Tripathi, H. Isobe, R. Jain
Since the first reports of oscillations in prominences in 1930s there have been major theoretical and observational advances to understand the nature of these oscillatory phenomena…
