Uvbyh Photometry of Main Sequence a Type Stars ?
نویسنده
چکیده
We present Strr omgren uvby and H photometry for a set of 575 northern main sequence A type stars, most of them belonging to the Hipparcos Input Catalogue, with V from 5 m to 10 m and with known radial velocities. These observations enlarge the catalogue we began to compile some years ago to more than 1500 stars. Our catalogue includes kinematic and astrophysical data for each star. Our future goal is to perform an accurate analysis of the kinematical behaviour of these stars in the solar neighbourhood.

An Analysis of the Currently Available Calibrations in Strr Omgren Photometry by Using Open Clusters
In recent years, several authors have revised the calibrations used to compute physical parameters (Mv, T ee , log g, Fe=H]) from intrinsic colours in the uvbyH photometric system. For reddened stars, these intrinsic colours can be computed through the standard relations among colour indices for each of the regions deened by Strr omgren (1966) on the HR diagram. We present a discussion of the c...
متن کاملPhotometric and spectroscopic study of the young open cluster NGC 1893
We present uvbyβ CCD photometry of the field of the open cluster NGC 1893. Our photometry is deep enough to cover the complete main sequence B spectral type. We identify ∼ 50 very likely members of the cluster down to spectral type B9-A0, some of which have much higher reddenings than the average. We derive a color excess E(b − y) = 0.33 ± 0.03 and a dereddened distance modulus V0 −MV = 13.9± 0...
متن کاملNGC 146: A young open cluster with a Herbig Be star and intermediate mass pre-main sequence stars
We present UBV CCD photometry and low-resolution spectra of stars in the field of the young open cluster NGC 146. UBV photometry of 434 stars were used to estimate the E(B−V) reddening of 0.55 ± 0.04 mag and BV photometry of 976 stars were used to estimate a distance modulus of (m−M)0 = 12.7 ±0.2 mag, corresponding to a distance of 3470 −305 pc. We estimated 10 – 16 Myr as the turn-off age for ...
متن کاملThe Distance to Ngc 6397 by M-subdwarf Main-sequence Fitting
Recent years have seen a substantial improvement both in photometry of low-luminosity stars in globular clusters and in modeling the stellar atmospheres of late-type dwarfs. We build on these observational and theoretical advances in undertaking the Ðrst determination of the distance to a globular cluster by main-sequence Ðtting using stars on the lower main sequence. The calibrating stars are ...
متن کاملInfrared Space Observ at Ory Photometric Search of Main-sequence Stars for Vega-type Systems1
We obtained 3.6È20 km photometry of 38 bright [IRAS km)[ 0.7 Jy] main-sequence stars with Fl(12 the Infrared Space Observatory (ISO). Observations were conducted with the ISOPHOT instrument, in the single-pointing photometry mode, through Ðlters at 3.6, 11.5, and 20.0 km. We searched for excess (Vega-type) emission from dust at temperatures K, located at D1È60 AU from the stars. We thus Z100 sa...
