We present observations of CK Vul obtained with the Spitzer Space Telescope. The infrared spectrum reveals a warm dust continuum with nebular, molecular hydrogen and HCN lines superimposed, together with the `Unidentified Infrared' features. The nebular lines are consistent with emission by a low-density gas. We conclude that the Spitzer data, combined with other information, are incompatible with CK Vul being a classical nova remnant in `hibernation' after the event of 1670, a `very late… Expand

Elemental abundances in the remnant of the ancient eruption of CK Vulpeculae.
CK Vul or Nova 1670 is an enigmatic eruptive object which underwent a stellar-merger event recorded by seventeenth-century observers. Its remnant was recently recovered at submillimeter wavelengths,Expand
Organic molecules, ions, and rare isotopologues in the remnant of the stellar-merger candidate, CK Vulpeculae (Nova 1670)
CK Vul is a star whose outburst was observed in 1670-72. A stellar-merger event was proposed to explain its ancient eruption. Aims: We aim to investigate the composition of the molecular gas recentlyExpand
ALMA reveals the aftermath of a white dwarf–brown dwarf merger in CK Vulpeculae
We present Atacama Large Millimeter–Submillimeter Array (ALMA) observations of CK Vulpeculae which is identified with “Nova Vulpeculae 1670”. They trace obscuring dust in the inner regions of theExpand
Astronomical detection of radioactive molecule 26AlF in the remnant of an ancient explosion
Decades ago, γ-ray observatories identified diffuse Galactic emission at 1.809 MeV1–3 originating from β+ decays of an isotope of aluminium, 26Al, that has a mean lifetime of 1.04 million years4.Expand
Molecular remnant of Nova 1670 (CK Vulpeculae)
CK Vul erupted in 1670 and is considered a stellar-merger candidate. Its remnant contains a molecular component of surprisingly rich composition. We present interferometric line surveys withExpand
Molecular remnant of Nova 1670 (CK Vulpeculae)
CK Vul is the remnant of an energetic eruption known as Nova 1670 that is thought to be caused by a stellar merger. The remnant is composed of (1) a large hourglass nebula of recombining gas (ofExpand
Near-infrared Spectroscopy of CK Vulpeculae: Revealing a Remarkably Powerful Blast from the Past
CK Vulpeculae, which erupted in AD 1670-71, was long considered to be a nova outburst; however, recent observations have required that alternative scenarios be considered. Long slit infraredExpand


CK Vul: reborn perhaps, but not hibernating
ABSTRA C T It has been claimed that CK Vul (the remnant of Nova Vul 1670) may be the oldest recovered ‘old nova’ and as such provides evidence in support of the hibernation scenario for classicalExpand
The enigma of the oldest ‘nova’: the central star and nebula of CK Vul
CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova, or a very late thermal pulse object. Following its eruption in AD 1670, the star remained visible for 2 years. AExpand
Atypical dust species in the ejecta of classical novae
A classical nova outburst arises from a thermonuclear run- away in the hydrogen-rich material accreted onto the surface of a white dwarf in a binary system. These explosions can produce copiousExpand
An observational case against nova hibernation
We use WHT spectroscopy and imaging to show that nova Vul 1670 (= CK Vul) has been incorrectly identified, and thus its luminosity cannot be used as evidence that novae fade into a 'hibernation'Expand
Infrared spectroscopy of Nova Cassiopeiae 1993 ¿ IV. A closer look at the dust
Nova Cassiopeiae 1993 (V705 Cas) was an archetypical dust-forming nova. It displayed a deep minimum in the visual light curve, and spectroscopic evidence for carbon, hydrocarbon and silicate dust. WeExpand
Nuclear ashes and outflow in the eruptive star Nova Vul 1670
It is reported that CK Vul is surrounded by chemically rich molecular gas in the form of an outflow, as well as dust, revealing that CK Vul's composition was strongly enhanced by the nuclear ashes of hydrogen burning. Expand
Elemental Abundances in the Ejecta of Old Classical Novae from Late-Epoch Spitzer Spectra
We present Spitzer Space Telescope mid-infrared IRS spectra, supplemented by ground-based optical observations, of the classical novae V1974 Cyg, V382 Vel, and V1494 Aql more than 11, 8, and 4 yearsExpand
CK Vul: evolving nebula and three curious background stars
We analyse the remnants of CK Vul (Nova Vul 1670) using optical imaging and spectroscopy. The imaging, obtained between 1991 and 2010, spans 5.6% of the life-time of the nebula. The flux of theExpand
CK Vul as a candidate eruptive stellar merging event
CK Vul (Nova Vul 1670) is one of the most mysterious objects among erupting stellar objects. Past studies have sug- gested that CK Vul is a final helium-flash object resembling V605 Aql and V4334 SgrExpand
