A possible orbital period for the dwarf nova V1101 Aql⋆
We have performed a Discrete Fourier Transform on 136 CCD B, V and R frames of the Z Cam–type dwarf nova V1101 Aql. Our analysis indicates as possible orbital period Porb = 3 .46, though we cannot exclude the alias at 4.00. We estimate the distance to the system to be about 300 pc. We possibly discovered a bright bow–shaped nebulosity around the object.
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
On the MV (peak) Versus Orbital Period Relation for Dwarf Nova Outbursts
We present computations for the accretion disk limit cycle model in an attempt to explain the empirical relation for dwarf nova outbursts between the peak visual absolute magnitude and orbital period found by Warner. For longer period systems one sees intrinsically brighter outbursts. This is accounted for in the limit cycle model by the scaling with radius of the critical surface density Σmax ...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
CSS100603:112253111037: a heliumrich dwarf nova with a 65min orbital period
We present time-resolved optical spectroscopy of the dwarf nova CSS100603: 112253−111037. Its optical spectrum is rich in helium, with broad, double-peaked emission lines produced in an accretion disc. We measure a line flux ratio He I λ5876/Hα = 1.49 ± 0.04, a much higher ratio than is typically observed in dwarf novae. The orbital period, as derived from the radial velocity of the line wings,...
