Infrared properties of Planetary Nebulae with PG1159 central stars
C. Muthumariappan, K. Khushbu, V. Kerni
We study the properties of 26 PNe with PG1159-type central stars known till date and compare them with the properties of PNe having [WR], and hydrogen-rich central stars pub…
Photo-ionization structures of Planetary Nebula IC 2003 with [WR] central star
Khushbu K., C. Muthumariappan
We present ionization structures of IC 2003, a planetary nebula with [WR] central star, using a 1-D dusty photo-ionization code: "CLOUDY 17.03". The photo-ionization model is const…
Probing infrared excess connection with Li enhancement among red clump giants
Anohita Mallick, Bacham E. Reddy, C. Muthumariappan
We have performed a search among low mass red giants for finding evidence for merger scenario for triggering He-flash and subsequent Li enhancement. We chose a sample of red giants…
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…
Binarity and Accretion in AGB Stars: HST/STIS Observations of UV Flickering in Y Gem
R. Sahai, C. Sánchez Contreras, A. Mangan +3
Binarity is believed to dramatically affect the history and geometry of mass loss in AGB and post-AGB stars, but observational evidence of binarity is sorely lacking. As part of a…
