A simple method of correcting magnitudes for the errors introduced by atmospheric refraction
A. Kruszewski, I. Semeniuk
We show that the errors due to atmospheric refraction are present in the magnitudes determined with the Difference Images Analysis method. In case of single, unblended stars the si…
Detached Eclipsing Binaries for Parallax Measurement
Irena Semeniuk
A list of 50 bright Detached Eclipsing Binaries proposed for precise parallax measurements for the FAME is presented. The eclipsing binaries, with precise distances and with photom…
Comparison of Parallaxes from Eclipsing Binaries Method with Hipparcos Parallaxes
Irena Semeniuk
The parallaxes determined by Lacy (1979) by means of eclipsing binaries method are compared with the Hipparcos parallaxes for 19 systems. The residual scatter of the distance modul…
Nearby Hipparcos Eclipsing Binaries for Color - Surface Brightness Calibration
A. Kruszewski, I. Semeniuk
This paper contains the list of Hipparcos eclipsing binaries that fulfill the following conditions: the star is classified in the Hipparcos Catalogue as EA-type eclipsing binary an…
CCD Photometry of SW Ursae Majoris during the 1996 Superoutburst
I. Semeniuk, A. Olech, T. Kwast +1
We present CCD R photometry of SW Ursae Majoris - an SUUMa type cataclysmic variable - obtained during its April 1996 superoutburst. The mean value of the superhump period derived…
CCD Photometry of Nova V1500 Cygni Twenty Years After
I. Semeniuk, A. Olech, M. Nalezyty
We report on CCD photometry of Nova V1500 Cygni obtained in July 1995 to show that twenty years after outburst, being of about 18~mag, the star can still be observed with small tel…
