FG Sge: new multicolor photometry and short-term dust shell clearing in 2019
V. P. Arkhipova, N. P. Ikonnikova, V. I. Shenavrin +6
We present the results of a new stage of the long-term photometric study of FG Sge which is a quickly evolving central star of the planetary nebula Hen 1-5. Our new observations ca…
Supernova 2018aoq and a distance to Seyfert galaxy NGC 4151
D. Yu. Tsvetkov, P. V. Baklanov, M. Sh. Potashov +9
We present optical photometric observations of SN 2018aoq from 2 to 100 days after explosion, and 7 spectra at epochs from 11 to 71 days. The light curves and spectra are typical f…
The light curves of type II-P SN 2017eaw: first 200 days
D. Yu. Tsvetkov, S. Yu. Shugarov, I. M. Volkov +7
We present UBVRI photometry of the supernova 2017eaw in NGC 6946, obtained in the period from May 14 until December 7, 2017. We derive dates and magnitudes of maximum light in the…
Photometry and spectroscopy of SN 2015bh in the galaxy NGC 2770
V. P. Goranskij, E. A. Barsukova, A. F. Valeev +4
We present medium-resolution spectroscopy and multicolor photometry for the optical transient PSN J09093496+3307204 (SN 2015bh) in the galaxy NGC 2770, which has transferred into t…
PSN J07285387+3349106 in NGC 2388: an extremely rapidly declining luminous supernova
D. Yu. Tsvetkov, I. M. Volkov, N. N. Pavlyuk
We present CCD BVRI photometry for PSN J07285387+3349106 in NGC 2388 collected from 2015 February 17 until March 17. Decaying by 3.6 mag in the R band in the first 20 days post-max…
Massive stars exploding in a He-rich circumstellar medium. IV. Transitional Type Ibn Supernovae
A. Pastorello, S. Benetti, P. J. Brown +30
We present ultraviolet, optical and near-infrared data of the Type Ibn supernovae (SNe) 2010al and 2011hw. SN 2010al reaches an absolute magnitude at peak of M(R) = -18.86 +- 0.21.…
