Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
An astrometric and spectroscopic study of the Scuti variable HD21190 and its wide companion CPD -83 64B
E. Niemczura, R. -D. Scholz, S. Hubrig +4
Although pulsations of Scuti type are not expected among Ap stars from a theoretical point of view, previous observations of the known Scuti star HD21190 indicated a spectr…
Magnetized strange quark matter in gravity with bilinear and special form of time varying deceleration parameter
P. K. Sahoo, Parbati Sahoo, Binaya K. Bishi +1
In this paper, we have studied homogeneous and anisotropic, locally rotationally symmetric (LRS) Bianchi type-I universe model with magnetized strange quark matter (MSQM) distribut…
High-resolution spectroscopy and abundance analysis of Delta Scuti stars near the Gamma Doradus instability strip
F. Kahraman Aliçavuş, E. Niemczura, M. Polińska +5
Scuti stars are remarkable objects for asteroseismology. In spite of decades of investigations, there are still important questions about these pulsating stars to be answered,…
Eclipsing binary stars with a Scuti component
F. Kahraman Aliçavuş, E. Soydugan, B. Smalley +1
Eclipsing binaries with a Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of 6…
Radio and optical intra-day variability observations of five blazars
X. Liu, P. P. Yang, J. Liu +23
We carried out a pilot campaign of radio and optical band intra-day variability (IDV) observations of five blazars (3C66A, S5 0716+714, OJ287, B0925+504, and BL Lacertae) on Decemb…
