Multicolor photometry and spectroscopy of the yellow supergiant with dust envelope HD 179821=V1427 Aquilae
N. P. Ikonnikova, O. G. Taranova, V. P. Arkhipova +5
We present the results of multicolor (UBVJHKLM) photometry (2009-2017) and low-resolution spectroscopy (2016-2017) of the semi-regular variable V1427 Aql=HD 179821, a yellow superg…
Photometric and Spectroscopic Study of the Supergiant with an Infrared Excess V1027 Cygni
V. P. Arkhipova, O. G. Taranova, N. P. Ikonnikova +4
We present the results of our and -photometry for the semiregular pulsating variable V1027~Cyg, a supergiant with an infrared excess, over the period from 1991 to 2015…
Comparison of the infrared magnitudes of the eclipsing variable star epsilon Aur during the two main luminance lows using observations from 1980 to 2015
I. A. Maslov, O. G. Taranova, A. M. Tatarnikov +1
The data of photometric measurements of the long-period eclipsing variable epsilon Aur in the two main minima 1982 and 2010 in the spectral range of 1--5 microns are presented. Not…
Reverberation measurement of the inner radius of the dust torus in NGC 4151 during 2008-2013
V. L. Oknyansky, N. V. Metlova, O. G. Taranova +4
We investigate the correlation between infrared (JHKL) and optical (B) fluxes of the variable nucleus of the Seyfert galaxy NGC 4151 using partially published data for the last 6 y…
Bright OB stars in the Galaxy - III. Constraints on the radial stratification of the clumping factor in hot star winds from a combined Halpha, IR and radio analysis
J. Puls, N. Markova, S. Scuderi +4
Recent results strongly challenge the canonical picture of massive star winds: various evidence indicates that currently accepted mass-loss rates, Mdot, may need to be revised down…
Correlation of IR and Opticical Variability in NGC4151
V. L. Oknyanskij, V. M. Lyuty, O. G. Taranova +1
We combine all published NIR and optical photometrical observations of NGC 4151 as well as our new unpublished yet data which can be used for determination of time delays between o…
