Spectroscopic Variability of the Compact Planetary Nebula Hb 12
N. P. Ikonnikova, I. A. Shaposhnikov, V. F. Esipov +5
We present the results of our new low-resolution spectroscopic observations of the young compact planetary nebula Hb 12 performed in 2011-2020 with SAI MSU telescopes. We have meas…
First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z<0.6
S. Sazonov, M. Gilfanov, P. Medvedev +22
We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0<l<180…
Discovery of orbital Eccentricity and Evidence for orbital Period Increase of SS433
A. M. Cherepashchuk, A. A. Belinski, A. V. Dodin +1
The examination of long-term (1979-2020) photometric observations of SS433 enabled us to discover a non-zero orbital eccentricity of We have also found evidence f…
Peculiar X-ray transient SRGA J043520.9+552226/AT2019wey discovered with SRG/ART-XC
I. A. Mereminskiy, A. V. Dodin, A. A. Lutovinov +24
Context: During the ongoing all-sky survey, the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory should discover new X-ray sources, many of which can be transient. H…
The collimated propagation causes of astrophysical and laboratory jets
I. Kalashnikov, A. Dodin, I. Il'ichev +2
The use of Z-pinch facilities makes it possible to carry out well-controlled and diagnosable laboratory experiments to study laboratory jets with scaling parameters close to those…
Propagation dynamics of successive emissions in laboratory and astrophysical jets and problem of their collimation
I. Kalashnikov, P. Chardonnet, V. Chechetkin +2
The paper presents the results of numerical simulation of the propagation of a sequence of plasma knots in laboratory conditions and the astrophysical environment. The physical and…
