Lightcurves of nine asteroids, with pole and sense of rotation of 42 Isis

Photometry and models of selected main belt asteroids

“…They obtained a period of 6.15 h, similar to that reported by Erikson (1990). Denchev et al (1998) consistent with the values given by Debehogne et al (1990) and Erikson (1990).…”

“…A 0.60-m Cassegrain telescope equipped with a single-channel photometer was used at the Rhozen Observatory (Bulgaria). The transformation to the UBV standard system was carried out with standard algorithms (Denchev et al 1998).…”

Photometry and models of selected main belt asteroids I. 52 Europa, 115 Thyra, and 382 Dodona

“…A 0.60 m Cassegrain telescope equipped with a single-channel photometer was used at the Rhozen Observatory (Bulgaria). A transformation to the UBV standard system has been carried out with standard algorithms (Denchev et al 1998). Unfiltered photometry was carried out at the University of Szeged (Hungary) using a 0.28 m telescope and SBIG ST-6 CCD-camera.…”

CCD photometry, spin and shape models of five asteroids: 225, 360, 416, 516, and 1223

“…A 60-cm Cassegrain telescope equipped with a single-channel photometer was used at the Rhozen Observatory (Bulgaria). A transformation to the UBV standard system has been carried out with standard algorithms (Denchev et al 1998). One lighturve of this object was obtained at Borowiec Station of the Poznan Observatory (Poland), with a 25-cm Newton reflector and a KAF-400 CCD camera.…”

“…New CCD photometric observations for 225 Henrietta (1995), 360 Carlova (1996, 1997, 1998), 416 Vaticana (1995-96, 1998), 516 Amherstia (1995, 1996, and 1223 Neckar (1995-96) carried out at five observatories are presented. New synodical periods for two asteroids (225, 1223) have been obtained.…”
