We describe four different approaches for the detection of magnetospheric accretion among Herbig Ae/Be stars with accretion disks. Studies of several unique objects have been carried out. One of the objects is the Herbig Ae star HD 101412 with a comp

Accretion-driven spin-up of a magnetized white dwarf in a close binary system is discussed. We address a situation in which the magnetic field of the white dwarf is screening during the accretion phase and re-generating due to the field diffusion thr

The most striking feature of the close binary system AE Aqr is its unique photometric behaviour - irregular alternations of quiet and active phases without noticeable transition periods. Although extensive photometric observations of AE Aqr have been

The spin-down power of the white dwarf in the close binary AE Aquarii significantly exceeds the bolometric luminosity of the system. The interpretation of this phenomenon in terms of the gravitational-wave emitter mechanism has been recently suggeste

Study of observed spin evolution of long-period X-ray pulsars challenges quasi-spherical and Keplerian disk accretion scenarios. It suggests that the magnetospheric radius of the neutron stars is substantially smaller than Alfven radius and the spin-

Analysis of line profiles allows the geometric and kinematic characteristics of gaseous inhomogeneities to be determined. In addition, multi-colour polarimetry makes it possible to study the structure of the circumstellar medium close to the star, an

The 33s.08 oscillation and its second harmonic in the optical light of AE Aqr, detected by Patterson (1979; ApJ 234, 978) and being due to hot magnetic pole caps rotating in and out of sight, are considered a persistent characteristic of the system.

Simultaneous high-resolution spectroscopy in Ha and UBVRI polarimetric observations are proposed as an effective method for the search for circumstellar inhomogeneities in A0-type Herbig stars. The new results for AB Aur are presented as a successful
