Chromospheric features of LQ Hydrae from Hα line profiles
We analyze the Hα spectral variability of the rapidly-rotating K1-dwarf LQ Hya using high-resolution Hα spectra recorded during April-May 2000. Chromospheric parameters were computed from the Hα profile as a function of rotational phase. We find that all these parameters vary in phase, with a higher chromospheric electron density coinciding with the maximum Hα emission. We find a clear rotation...
متن کاملModelling the time variation of the surface differential rotation in AB Doradus and LQ Hydrae
Sequences of Doppler images of the young, rapidly rotating late-type stars AB Dor and LQ Hya show that their equatorial angular velocity and the amplitude of their surface differential rotation vary versus time. Such variations can be modelled to obtain information on the intensity of the azimuthal magnetic stresses within stellar convection zones. We introduce a simple model in the framework o...

Photometric Observations of Supernovae 2000 E , 2001
CCD BV RI photometry is presented for two type Ia supernovae 2000E and 2001V, for SN Ib 2001B and SN II-P 2001X. The parameters of light curves and absolute magnitudes at maximum light are estimated. It is shown that all four supernovae are typical for their classes considering the shape of their light curves and maximum luminosity.
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
