Long term optical variability of two HMXB
Roberto Nesci, Mariateresa Fiocchi, Antonio Vagnozzi
We discuss the optical light curves of two Be X-ray Binaries, IGR J06074+2205 and SAX J2103.5+4545 recovered from the ATLAS, ZTF and ASAS-SN databases. Both sources show long term…
ASASSN-18aan revisited
Roberto Nesci, Antonio Vagnozzi, Stefano Valentini
The light curve of the cataclismic variable ASASSN-18aan is studied using recent observations of the MC589 Observatory, giving an orbital Period and Epoch fully consistent with the…
Period changes of Mira variables in the M16-M17 region
Roberto Nesci, Igor Soszyński, Taavi Tuvikene
We analyzed the light curves of 165 AGB variables, mostly Miras, in the sky area centered between M16 and M17 (l=16, b=0), using the OGLE GVS database in the I_C band. Comparison w…
Search for period changes in Mira stars
Roberto Nesci, Gianni Rocchi
We reobserved in the and bands, during the years 2020-2021, seven Mira variables in Cassiopeia, for which historical light curves were available fro…
Multi-wavelength flare observations of the blazar S5 1803+784
R. Nesci, S. Cutini, C. Stanghellini +8
The radio, optical, and -ray light curves of the blazar S5 1803+784, from the beginning of the {\it Fermi} Large Area Telescope (LAT) mission in August 2008 until December 2018,…
The large gamma-ray flare of the FSRQ PKS 0346-27
R. Angioni, R. Nesci, J. D. Finke +2
In this paper, we characterize the first -ray flaring episode of the FSRQ PKS 0346-27 (z=0.991), as revealed by Fermi-LAT monitoring data, and the concurrent multi-wavelength va…
