Time Lag between Accretion and Wind Events in the T Tauri Star RY Tau
E. V. Babina, P. P. Petrov, K. N. Grankin +1
The results of spectroscopic and photometric monitoring of the classical T Tauri star RY Tau are presented. The observation series span 220 nights from 2013 to 2024. During the obs…
Density streams in the disc winds of Classical T Tauri stars
P. P. Petrov, K. N. Grankin, E. V. Babina +5
Spectral and photometric variability of the Classical T Tauri stars RY Tau and SU Aur from 2013 to 2022 is analyzed. We find that in SU Aur the H-alpha line's flux at radial veloci…
Jet from the enigmatic high-latitude star BP Psc and evolutionary status of its driving source
I. S. Potravnov, M. Yu. Khovritchev, S. A. Artemenko +1
BP Psc is an active late-type (sp:G9) star with unclear evolutionary status lying at high galactic latitude . It is also the source of the well collimated bipolar je…
Modulated accretion in T Tauri star RY Tau -- stable MHD propeller or a planet at 0.2 AU?
P. P. Petrov, M. M. Romanova, K. N. Grankin +3
Planets are thought to form at the early stage of stellar evolution when the mass accretion is still ongoing. RY Tau is a T Tauri type star at the age of a few Myr, with accretion…
Dynamics of wind and the dusty environments in the accreting T Tauri stars RY Tau and SU Aur
P. P. Petrov, K. N. Grankin, J. F. Gameiro +10
Classical T Tauri stars with ages of less than 10 Myr possess accretion discs. Magnetohydrodynamic processes at the boundary between the disc and the stellar magnetosphere control…
The beta Pictoris association low-mass members: membership assessment, rotation period distribution, and dependence on multiplicity
S. Messina, A. C. Lanzafame, L. Malo +6
Low-mass members of young stellar associations exhibit a wide spread of rotation periods. Such a spread originates from distributions of masses and initial rotation periods. Howeve…
The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
S. Messina, M. Millward, A. Buccino +19
We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic proper…
Wind Dynamics and Circumstellar Extinction Variations in the T Tauri Star RY Tau
Elena V. Babina, Svetlana A. Artemenko, Peter P. Petrov
The wind interaction with the dusty environment of the classical T Tauri star RY Tau has been investigated. During two seasons of 2013-2015 we carried out a spectroscopic and photo…
The visual binary AG Tri in Pictoris Association: can a debris disc cause very different rotation periods of its components?
Sergio Messina, Miguel Muro Serrano, Svetlana Artemenko +3
We measure the photometric rotation periods of the components of multiple systems in young stellar associations to investigate the causes of the observed rotation period dispersion…
Another deep dimming of the classical T Tauri star RW Aur A
P. P. Petrov, G. F. Gahm, A. A. Djupvik +3
Context. RW Aur A is a classical T Tauri star (CTTS) with an unusually rich emission line spectrum. In 2014 the star faded by ~ 3 magnitudes in the V band and went into a long-last…
Facing the wind of the pre-FUor V1331 Cyg
P. P. Petrov, R. Kurosawa, M. M. Romanova +4
The mass outflows in T Tauri stars (TTS) are thought to be an effective mechanism to remove angular momentum during the pre-main-sequence contraction of a low-mass star. The most p…
The Monitor Project: Stellar rotation at 13~Myr: I. A photometric monitoring survey of the young open cluster h~Per
E. Moraux, S. Artemenko, J. Bouvier +9
We aim at constraining the angular momentum evolution of low mass stars by measuring their rotation rates when they begin to evolve freely towards the ZAMS, i.e. after the disk acc…
Rotation Effects in Classical T Tauri Stars
Svetlana A. Artemenko, Konstantin N. Grankin, Peter P. Petrov
Surface temperature inhomogeneities in classical T Tauri stars (CTTS) induced by magnetic activity and mass accretion lead to rotational modulation of both photometric and spectros…
Accretion-powered chromospheres in classical T Tauri stars
P. P. Petrov, G. F. Gahm, H. C. Stempels +2
(Abridged) Optical spectra of classical T Tauri stars (cTTS) are rich in emission lines of low-excitation species that are composed of narrow and broad components, related to two r…
Search for Keplerian periods in light variations of T Tauri stars and Herbig Ae stars
S. A. Artemenko, K. N. Grankin, P. P. Petrov
Long-term, uniform series of UBVR observations of T Tauri and Herbig Ae stars obtained over 20 yr at the Maidanak Observatory as part of the ROTOR program are analyzed. We find a l…
Dynamo Processes in the T Tauri star V410 Tau
M. B. Skelly, J. -F. Donati, J. Bouvier +4
We present new brightness and magnetic images of the weak-line T Tauri star V410 Tau, made using data from the NARVAL spectropolarimeter at Telescope Bernard Lyot (TBL). The bright…
