Noctilucent Clouds Modulated by Strong 5-day Planetary Wave in 2025: Amplitudes, Phases and Altitudes Based on Ground-Based Observations and Satellite Temperature Data
Oleg S. Ugolnikov, Ilya S. Yankovsky, Nikolay N. Pertsev +12
During the summer season of 2025, noctilucent clouds (NLC) were observed at the latitudes 55-60N from the late May until the late August. A distinct 5-day periodicity in their occu…
The jet of BP Tau
A. V. Dodin, S. A. Potanin, M. A. Burlak +6
A strong global magnetic field of young low-mass stars and a high accretion rate are the necessary conditions for the formation of collimated outflows (jets) from these objects. Bu…
Optical Identification and Spectroscopic Redshift Measurements of 216 Galaxy Clusters from the SRG/eROSITA All-Sky Survey
I. A. Zaznobin, R. A. Burenin, A. A. Belinski +34
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectrosco…
ZZ Tau IRS: a low mass UX Ori type star with strong wind
M. A. Burlak, A. V. Dodin, A. V. Zharova +7
The results of photometric, polarimetric and spectroscopic observations of the young star ZZ Tau IRS in the visible and near-infrared bands are presented. Against the continuum of…
TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70
Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…
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…
