We report the results of a 20 year campaign to monitor the infrared (IR) spectral energy distribution (SED) of the "born again" star FG Sge, which is embedded in an old planetary nebula. The IR data show that the central star apparently reestablished an essentially steady state post-asymptotic giant branch (AGB) type wind in late 1992. Since then, the visual light curve has shown irregular large amplitude variations on timescales of 200-400 days, while the IR SED has maintained a constant… Expand
INFRARED SPECTROSCOPY OF SYMBIOTIC STARS. IX. D-TYPE SYMBIOTIC NOVAE
Time-series spectra of the near-infrared 1.6 {mu}m region have been obtained for five of the six known D-type symbiotic novae. The spectra map the pulsation kinematics of the Mira component in theExpand
THE SPATIALLY RESOLVED BIPOLAR NEBULA OF SAKURAI'S OBJECT
Sakurai's object (V4334 Sgr), the final flash object discovered in the mid-1990s, underwent rapid cooling during the first decade of the 21st century becoming as faint as K ∼ 25. This stage ofExpand
The infrared view of dust and molecules around V4334 Sgr (Sakurai’s object): a 20-yr retrospective
Abstract We present an analysis of the evolution of circumstellar dust and molecules in the environment of the very late thermal pulse object V4334 Sgr (Sakurai’s Object) over a ∼20-year period,Expand
Imaging ejecta from the final flash star V605 Aquilae
Aims. We investigated the cloud of ejecta resulting from the mass loss associated with the final helium shell flash in V605 Aql. Methods. V605 Aql was imaged at high spatial resolution in bothExpand
The Elemental Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars
We review the observed properties of extremely hot, hydrogen-deficient post-asymptotic giant branch (AGB) stars of spectral type (WC) and PG1159. Their H deficiency is probably caused by a (very)Expand
The circumstellar dust of "Born-Again" stars
We describe the evolution of the carbon dust shells around Very Late Thermal Pulse (VLTP) objects as seen at infrared wavelengths. This includes a 20-year overview of the evolution of the dust aroundExpand
FG SGE: Evolution of the circumstellar dust shell (JHKLM Photometry in 1985–2013)
Long-term (1985–2013) JHKLM photometry for FG Sge is analyzed. Parameters of the supergiant and optical properties of the dust in the dust shell (DS) have been refined. Given the optical photometry,Expand
Stellar Populations and Mass Loss in M15: A Spitzer Space Telescope Detection of Dust in the Intracluster Medium
We present Spitzer Space Telescope IRAC and MIPS observations of the Galactic globular cluster M15 (NGC 7078), one of the most metal-poor clusters, with a [Fe/H] = -2.4. Our Spitzer images reveal aExpand
The Temperature and Density from Permitted O II Lines in the Planetary Nebula NGC 7009
We present spatialand velocity-resolved spectroscopy of NGC 7009 acquired with the UVES spectrograph at the VLT UT2/Kueyen. We use these data to determine the structure of the electron temperatureExpand
Astrophysics in 2005
We bring you, as usual, the Sun and Moon and stars, plus some galaxies and a new section on astrobiology. Some highlights are short (the newly identified class of gamma-ray bursts, and the DeepExpand

We suggest that supernova 1987a may condense dust of substantial visual optical thickness as do many novae. The dust will act as a calorimeter of the photon luminosity of any central engine that isExpand
