The period-luminosity relation for Cepheids derived from multiphase temperature measurements and Cepheids kinematics based on GAIA DR2 data
Yaroslav A. Lazovik, Alexey S. Rastorguev, Marina V. Zabolotskikh +1
Calibration of the period-luminosity relation (PLR) for Cepheids has always been one of the biggest goals of stellar astronomy. Among a considerable number of different approaches,…
New version of the Baade--Becker--Wesselink method based on multiphase effective temperature measurements of Cepheids
Alexey S. Rastorguev, Yaroslav A. Lazovik, Marina V. Zabolotskikh +2
A new version of the Baade--Becker--Wesselink (hereafter BBW) method is proposed, based on direct spectroscopic measurements of effective temperatures of 45 northern Cepheids, made…
The Mass of the Cepheid V350 Sgr
Nancy Remage Evans, Charles Proffitt, Kenneth G. Carpenter +6
V350 Sgr is a classical Cepheid suitable for mass determination. It has a hot companion which is prominent in the ultraviolet and which is not itself a binary. We have obtained two…
Spectroscopic orbits of nearby solar-type dwarfs. II
N. A. Gorynya, A. Tokovinin
Several nearby solar-type dwarfs with variable radial velocity were monitored to find their spectroscopic orbits. First orbital elements of 15 binaries (HIP 12144, 17895, 27970, 32…
PZ Mon is a new synchronous binary with low mass ratio
Y. V. Pakhomov, N. A. Gorynya
Analysis of new radial velocity measurements of the active giant PZ Mon is presented. Only in 2015 was reported that PZ Mon may be classified as RS CVn giant. At the same time was…
Evolutionary status of the active star PZ Mon
Yu. V. Pakhomov, N. N. Chugai, N. I. Bondar +2
We use original spectra and available photometric data to recover parameters of the stellar atmosphere of PZ Mon, formerly referred as an active red dwarf. The derived effective te…
Spectroscopic orbits of ten nearby solar-type dwarfs
N. A. Gorynya, A. Tokovinin
Several nearby solar-type dwarfs with variable radial velocity were monitored to find their spectroscopic orbits. Orbital elements of HIP 179, 1989, 2981, 5276, 6439, 11218, 21443,…
The Baade-Becker-Wesselink technique and the fundamental astrophysical parameters of Cepheids
Alexey S. Rastorguev, Andrey K. Dambis, Marina V. Zabolotskikh +2
The BBW method remains one of most demanded tool to derive full set of Cepheid astrophysical parameters. Surface brightness version of the BBW technique was preferentially used dur…
Cepheid investigations using the Kepler space telescope
R. Szabó, L. Szabados, C. -C. Ngeow +35
We report results of initial work done on selected candidate Cepheids to be observed with the Kepler space telescope. Prior to the launch 40 candidates were selected from previous…
Angular Diameter Amplitudes of Bright Cepheids
P. Moskalik, N. A. Gorynya
Expected mean angular diameters and amplitudes of angular diameter variations are estimated for all monoperiodic Classical Cepheids brighter than <V> = 8.0mag. The catalog is inten…
Mean Angular Diameters and Angular Diameter Amplitudes of Bright Cepheids
P. Moskalik, N. A. Gorynya
We predict mean angular diameters and amplitudes of angular diameter variations for all monoperiodic Pop.I Cepheids brighter than <V> = 8.0mag. The catalog is intended to aid selec…
