      <abstract xml:lang="ru">
        <p>  Классические звезды типа Т Тельца (СTTS) находятся в ранней фазе эволюции, когда звезда окружена аккреционным диском. Большинство наблюдаемых явлений активности СTTS обусловлены процессами магнитосферной аккреции и ветра. В статье приводятся примеры наблюдений магнитосферной аккреции и образования эффекта вуалирования фотосферного спектра. Показано, что пыль, выносимая ветром с поверхности аккреционного диска, ответственна за наблюдаемую нерегулярную переменность блеска СTTS. В Крымской астрофизической обсерватории с 2013 г. проводится спектральный и фотометрический мониторинг двух звезд, RY Tau и SU Aur, с целью исследования динамики аккреции и ветра на временной шкале от нескольких суток до нескольких лет. Наблюдаемые изменения динамики газовых потоков могут быть вызваны как изменением темпа аккреции, так и изменением глобального магнитного поля молодой звезды.  </p>

        <p>  Classical T Tauri stars (CTTS) are at the early stage of evolution, when the processes of planet formation take place in the surrounding accretion disks. Most of the observed activity in CTTS is due to magnetospheric accretion and wind outflows. Observations of the accreting gas flows and appearance of the line-dependent veiling of the photospheric spectrum in CTTS are considered. Evidence for the dusty wind causing the observed irregular variability of CTTS is presented. Photometric and spectroscopic monitoring of two CTTS, RY Tau and SU Aur, has been carried out at the Crimean Astrophysical Observatory since 2013 aimed at studying the dynamics of accretion and wind flows on time scales from days to years. The observed variations in the dynamics parameters may be caused by changes in the accretion rate and in the global magnetic fields of CTTS.  </p>
