An empirical mass-loss law for Population II giants from the Spitzer-IRAC survey of Galactic globular clusters [PDF]
, 2014 The main aim of the present work is to derive an empirical mass-loss (ML) law for Population II stars in first and second ascent red giant branches.

The Search for Binaries in Post-Asymptotic Giant Branch Stars: Do Binary Companions Shape the Nebulae? [PDF]
Journal of Astronomy and Space Sciences, 2012 Binary companions are often invoked to explain the axial and point symmetry seen in the majority of planetary nebulae and proto-planetary nebulae (PPNs).

Evolution of the Outflow in the Water Fountain Source IRAS 18043–2116
The Astrophysical Journal, 2023 We present the spectral and spatial evolution of H _2 O masers associated with the water fountain source IRAS 18043−2116, found in observations with the Nobeyama 45 m Telescope and the Australia Telescope Compact Array. We have found new highest-velocity

Magnetic Flares on Asymptotic Giant Branch Stars [PDF]
, 2002 We investigate the consequences of magnetic flares on the surface of asymptotic giant branch (AGB) and similar stars. In contrast to the solar wind, in the winds of AGB stars the gas cooling time is much shorter than the outflow time.

EVOLUTION, NUCLEOSYNTHESIS, AND YIELDS OF LOW-MASS ASYMPTOTIC GIANT BRANCH STARS AT DIFFERENT METALLICITIES [PDF]
, 2009 The envelope of thermally pulsing asymptotic giant branch (TP-AGB) stars undergoing periodic third dredge-up (TDU) episodes is enriched in both light and heavy elements, the ashes of a complex internal nucleosynthesis involving p, α, and n captures over ...

Planetary Engulfment Prognosis within the ρ CrB System
The Astrophysical Journal, 2023 Exoplanets have been detected around stars at various stages of their lives, ranging from young stars emerging from formation to the latter stages of evolution, including white dwarfs and neutron stars.

A Superwind from Early Post-Red Giant Stars? [PDF]
, 2001 We suggest that the gap observed at 20,000 K in the horizontal branches of several Galactic globular clusters is caused by a small amount of extra mass loss which occurs when stars start to "peel off" the red giant branch (RGB), i.e., when their ...

Properties of the Variation of the Infrared Emission of OH/IR Stars III. The M Band Light Curves [PDF]
Journal of Astronomy and Space Sciences, 2010 To study properties of the pulsation in the infrared emission for long period variables, we have collected and analyzed the infrared observational data at M band for 12 OH/IR stars.

Multiple populations along the asymptotic giant branch of the globular cluster M 4 [PDF]
, 2016 Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with O-poor/Na-rich additional components.
