Long-term optical photometry of the PMS stars V2764 Ori and LkH 301 in the field of the McNeil's Nebula
G. Zidarova, S. Ibryamov, E. Semkov +1
In this paper, we present results from long-term photometric observations of the pre-main-sequence stars V2764 Ori and LkH 301, located in the field of the McNeil's…
Long-term optical photometric monitoring of the FUor star V900 Mon
Evgeni Semkov, Stoyanka Peneva, Sunay Ibryamov
We present results from photometric monitoring of V900 Mon, one of the newly discovered and still under-studied object from FU Orionis type. FUor phenomenon is very rarely observed…
New Results from Long-time Photometric Study of UX Orionis Star GM Cephei
Asen Mutafov, Evgeni Semkov, Stoyanka Peneva +1
New results from long-term optical photometric observations of the pre-main sequence star GM Cep from UX Orionis type are reported. During ongoing photometric monitoring of the GM…
Long-term CCD photometry of pre-main-sequence stars in the association Cepheus OB3
Sunay Ibryamov, Gabriela Zidarova, Evgeni Semkov +1
Results from optical CCD photometric observations of 13 pre-main-sequence stars collected during the period from February 2007 to November 2020 are presented. These stars are locat…
A new prolonged decrease event in the brightness of the young stellar object V2492 Cygni
Sunay Ibryamov, Evgeni Semkov
Results from the BV(RI)c photometric observations of the young stellar object V2492 Cyg collected in the period from April 2018 to September 2020 are presented. These observations…
Multi-Wavelength Variability of BL Lacertae Measured with High Time Resolution
Zachary R. Weaver, K. E. Williamson, S. G. Jorstad +54
In an effort to locate the sites of emission at different frequencies and physical processes causing variability in blazar jets, we have obtained high time-resolution observations…
