A Study of the relation between intensity oscillations and magnetic field parameters in a Sunspot: Hinode Observations
Ankala Raja Bayanna, Shibu K Mathew, Brajesh Kumar +2
We present properties of intensity oscillations of a sunspot in the photosphere and chromosphere using G~band and CaIIH filtergrams from Hinode. Intensity power maps as function of…
Investigation of the stellar content in the western part of the Carina nebula
Brajesh Kumar, Saurabh Sharma, Jean Manfroid +4
We obtained deep H photometric data of the field situated to the west of the main Carina nebula and centered on WR~22. Medium-resolution optical spectroscopy of a subsam…
Main-sequence variable stars in young open cluster NGC 1893
Sneh Lata, Ram Kesh Yadav, A. K. Pandey +5
In this paper we present time series photometry of 104 variable stars in the cluster region NGC 1893. The association of the present variable candidates to the cluster NGC 1893 has…
