Slowly Rotating Peculiar Star BD+001659 as a Benchmark for Stratification Studies in Ap/Bp Stars
A. Romanovskaya, T. Ryabchikova, Y. Pakhomov +2
We present the results of a self-consistent analysis of the magnetic silicon star BD+001659, based on its high-resolution spectra taken from the ESPaDOnS archive (R = 68,00…
Modelling the TESS light curve of Ap Si star MX TrA
Yu. Pakhomov, I. Potravnov, A. Romanovskaya +1
The TESS light curve of the silicon Ap star MX TrA was modelled using the observational surface distribution of silicon, iron, helium, and chromium obtained previously with the Dop…
On the surface distribution of chromium in Ap star HD 152564
I. S. Potravnov, T. A. Ryabchikova
The spectroscopic and photometric variability of magnetic Ap/Bp stars is caused by the surface inhomogeneities of their chemical composition (spots) that affect the structure of th…
Are the surface abundance structures stable in rapidly rotating Ap star 56 Ari?
I. Potravnov, N. Piskunov, T. Ryabchikova
The surface magnetic and abundance inhomogeneities in chemically peculiar Ap/Bp stars are coupled and responsible for their rotationally modulated variability. Within the framework…
Doppler imaging of a southern ApSi star HD 152564
I. Potravnov, T. Ryabchikova, N. Piskunov +2
We present the results of the spectroscopic study of a chemically peculiar star HD 152564. Using medium-resolution () observations obtained with the HRS spectrograph mount…
Magnetospheric accretion at the late phases of the Pre-Main-Sequence evolution. The case of RZ Psc
D. V. Dmitriev, V. P. Grinin, I. S. Potravnov +1
It has been shown that during the outburst of accretion activity observed in UX Ori type star RZ Psc in 2013, the accretion rate increased approximately by an order of magnitude. T…
BD+30549: young helium-weak silicon star in NGC 1333 star-forming region
I. Potravnov, L. Mashonkina, T. Ryabchikova
We present results of the spectroscopic study of the chemically peculiar star BD+30549 which is bona-fide member of young NGC 1333 star forming region. We found that the st…
