A New Approach to Calculate Coronal Electron Density: Simplified van de Hulst's Method
Hikmet Çakmak
Determining the electron density is a challenging task in solar corona studies, as it requires certain assumptions to be made, such as symmetric, homogeneous and radial distributio…
CCD UBV and Gaia DR3 based analysis of NGC 189, NGC 1758 and NGC 7762 open clusters
T. Yontan, S. Bilir, H. Cakmak +5
This paper presents photometric, astrometric, and kinematic analyses of the open clusters NGC 189, NGC 1758 and NGC 7762 based on CCD UBV photometric and Gaia Data Release 3 (DR3)…
Study of the Open Clusters in Kepler Prime Field
Yüksel Karataş, Hikmet Çakmak, İnci Akkaya Oralhan +3
We present a detailed study of NGC 6791, NGC 6811, NGC 6819 and NGC 6866, the four open clusters that are located in the Kepler prime field. We use new CCD UBV(RI)KC photometry, wh…
A study of the NGC 1193 and NGC 1798 open clusters using CCD UBV photometric and Gaia EDR3 data
T. Yontan, H. Cakmak, S. Bilir +8
We present photometric, astrometric, and kinematic studies of the old open star clusters NGC 1193 and NGC 1798. Both of the clusters are investigated by combining data sets from Ga…
