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…

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…

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…
