We carried out a Stroemgren photometric survey of thirteen southern bright stars, including {beta} Pictoris itself, during three years, d'Astrophysique de Paris, in order to...

We present uvby-{beta} photometry of 116 X-ray flux-selected active stars in the directions of the Orion (40), Taurus-Auriga (58) and Scorpius OB2-2 (18) star forming regions....

An extensive and up-dated list of {delta} Sct stars is presented here. More than 500 papers, published during the last few years, have been revised and 341 new variables have...

We present continuous multicolor photometry for 47 stars from October 1996 through June 1997. Altogether, 7073 V(RI)c, UBV, and by data points, each the average of three...

The tables give the results of the Stromgren photometry of the two southern open clusters NGC 6134 and NGC 3680, which were not printed in the paper in A&AS.

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for the magnetic CP stars 45 Leo, HR 4330, 49 Her,...

Differential Stroemgren uvby observations from the Four College Automated Photoelectric Telescope are presented for the mCP stars HD 35298, 19 Lyr, HD 192678, and HR 8216. The...

Differential Stroemgren uvby photometry obtained with the Four College Automated Photoelectric Telescope shows that the hot HgMn star 33 Gem is photometrically constant. The Si...

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for the ellipsoidal variable 33 Tauri, and the...

Complete uvby light curves of the detached Herbig Be eclipsing binary TY Coronae Australis are presented. A total of 1787 photometric measurements in each of the four colours...

Results of 131 stars from Renson's (1991, Cat. ) catalogue of Ap and Am stars observed with the {Delta}-a system are presented. With few exceptions the probability division of...

Stromgren and H{beta} photometry of 130 stars in the Carina section of the Milky Way is presented. The color excesses and the distances of all stars are obtained. A good...

The aim of this work is to study the capacity of the uvby H_{beta} system for detecting the chemically peculiar (CP) stars based on the effect that peculiar features in the flux...

Complete uvby light curves of the young detached double-lined massive O-type eclipsing binary V3903 Sagittarii, obtained from 1989 to 1994, are presented. The observations were...

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for four Chemically Peculiar stars of the upper main...

The table contains the differential magnitudes of CR Cas respect to comparison star SAO35044 indicating the time (Julian Date) a nd magnitudes in Stroemgren filters u, v, b, y

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for four magnetic chemically peculiar stars....

Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are used to examine the possible variability of the...

Complete uvby light curves of the detached triple-lined late B-type eclipsing binary V906 Scorpii, obtained from 1987 to 1991, are presented. A detailed photometric analysis...

Differential Stroemgren uvby photometric observations from the 0.75-m Four College Automated Photoelectric Telescope were obtained for three metallic-line and three...
