K-band spectra of selected post-AGB candidates
M. Parthasarathy, C. Muthumariappan, S. Muneer
We present medium resolution (1000) K-band spectra of 12 post-AGB candidates and related stars. For several objects in our sample, these spectra were obtained for the first time. T…
Infrared properties of Planetary Nebulae with [WR] and central stars
C. Muthumariappan, M. Parthasarathy
We report the IR properties of planetary nebulae with WR type and central stars known to date and compare them with the IR properties of a sample of PNe with H-rich central…
The puzzling high velocity G5 supergiant star HD 179821 : new insight from Gaia DR2 data
M. Parthasarathy, G. Jasniewicz, F. Thévenin
HD 179821 is classified as G5 Ia star. From the IRAS colors and spectral energy distributions it was classified as a post-AGB star. But some studies classify it as a massive (30 to…
Low resolution spectroscopy of selected Algol systems
D. Shanti Priya, J. Rukmini, M. Parthasarathy +4
The analysis of spectroscopic data for 30 Algol-type binaries is presented. All these systems are short period Algols having primaries with spectral types B and A. Dominant spectra…
Chemical composition of UV-bright star ZNG 4 in the globular cluster M13
S. Ambika, M. Parthasarathy, W. Aoki +4
We present a detailed model-atmosphere analysis of ZNG 4, a UV-bright star in the globular cluster M13. From the analysis of a high resolution () spectrum of th…
