Differential rotation of the solar transition region from STEREO/EUVI 30.4 nm images
Jaidev Sharma, Brajesh Kumar, Anil K Malik +1
The solar photosphere, chromosphere and corona are known to rotate differentially as a function of latitude. To date, it is unclear if the solar transition region also rotates diff…
A long term multi-frequency study of solar rotation using solar radio flux and its relationship with solar cycles
Vivek Kumar Singh, Satish Chandra, Sanish Thomas +2
This paper examines long-term temporal and spatial fluctuations in the solar rotation (more than four solar cycles) by investigating radio emission escapes from various layers of t…
Radial Differential Rotation of Solar Corona using Radio Emissions
Vivek Kumar Singh, Satish Chandra, Sanish Thomas +2
The present work is an effort to investigate possible radial variations in the solar coronal rotation by analyzing the solar radio emission data at 15 different frequencies (275-17…
Evidence of strong relationship between hemispheric asymmetry in solar coronal rotation and solar activity during solar cycle 24
Jaidev Sharma, Anil K Malik, Brajesh Kumar +1
In this article, we report an evidence of very high and statistically significant relationship between hemispheric asymmetry in solar coronal rotation rate and solar activity. Our…
On the variation of solar coronal rotation using SDO/AIA observations
Jaidev Sharma, Brajesh Kumar, Anil K. Malik +1
We report on the variability of rotation periods of solar coronal layers with respect to temperature (or, height). For this purpose, we have used the observations from Atmospheric…
Variations in the Solar Coronal Rotation with Altitude - Revisited
Hitaishi Bhatt, Rupal Trivedi, Som Kumar Sharma +1
Here we report in depth reanalysis of a paper by Vats et al. (2001) [Astrophys. J. 548, L87] based on the measurements of differential rotation with altitude as a function of obser…
Giant pulse emission from PSR B0950+08
Ashok K. Singal, Hari Om Vats
We present here the detection of giant-pulse emission from PSR B0950+08, a normal-period pulsar. The observations, made at 103 MHz and lasting for about ten months, have shown on a…
Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
Periodicities in the coronal rotation and sunspot numbers
Satish Chandra, Hari Om Vats
The present study is an attempt to investigate the long term variations in coronal rotation by analyzing the time series of the solar radio emission data at 2.8 GHz frequency for t…
North-South Asymmetry in the Solar Coronal Rotation
Hari Om Vats, Satish Chandra
The solar images at 17 GHz by Nobeyama Radio Heliograph and in X-ray by soft X-ray telescope (SXT) on board Yohkoh satellite have been of particular interest for the estimation of…
Differential rotation measurement of soft X-Ray corona
Satish Chandra, Hari Om Vats, K. N. Iyer
The aim of this paper is to study the latitudinal variation in the solar rotation in soft X-ray corona. The time series bins are formed on different latitude regions of the solar f…
Differential coronal rotation using radio images at 17 GHz
Satish Chandra, Hari Om Vats, K. N. Iyer
In the present work, we perform time-series analysis on the latitude bins of the solar full disk (SFD) images of Nobeyama Radioheliograph (NoRH) at 17 GHz. The flux modulation meth…
p-modes in and away from a sunspot
Brajesh Kumar, R. Jain, S. C. Tripathy +2
A time series of GONG Dopplergrams for the period 10-14 May 1997 from Udaipur and Big Bear sites has been used to measure the velocity fluctuations in the sunspot (NOAA active regi…
