K-Line Photometry of A Stars
A narrow-band spectrometer, compensated for seeing and transparency variations, has been constructed and used to measure the strength of the calcium K-line (3933.68{AA}) in 146... -
420nm CN and G bands in G8-K5 spectra
Measurements of the {lambda}4200{AA} CN band are presented for 712 late-type stars. G band data are also included for 212 of these stars. Mean errors of absolute magnitudes... -
Hydrogen-Line Absorption in Early-Type Stars
Photoelectric determinations of H-{gamma} absorption line intensity have been made of stars in selected clusters and associations as well as in the general galactic field.... -
Gaia DR2 x AllWISE catalogue
The second Gaia Data Release (DR2) contains astrometric and photometric data for more than 1.6 billion objects with mean Gaia G magnitude <20.7, including many Young Stellar... -
Narrow-band photometry of early-type stars
A compilation of the photoelectric measurements in the Barbier-Morguleff system is presented for 773 stars of spectral types O8 to F6. 706 stars have been measured at least... -
Photometry of orange-red CaI triplet in Late-Type Stars
Calcium absorption lines were measured using narrow-band photometry on 296 high and low velocity G8-K5 stars of all luminosity classes. Because the blue-violet region of the... -
Narrow-Band Photometry of Late-Type Stars
The catalog is a compilation of photoelectric photometry obtained as part of a program investigating the distribution of stars and stellar matter perpendicular to the galactic... -
Observations in the Geneva Photometric System 4.
This catalog is a successor to an earlier edition (Rufener 1981). It is a compilation of photoelectric measurements made in the Geneva Observatory seven-color photometric... -
Spectral Investigation of NGC 7469
This investigation is mainly related to hydrogen lines in the spectrum of NGC 7469 from the 1972-1990 data obtained using an image tube on the 2.6-m telescope of the Crimean... -
A search for variable stars in M4 with K2 LCs
We extract light curves for 4554 objects with 9<G<19 in the K2 superstamp observations of the globular cluster M4, including 3784 cluster members, and search for...
