The large amount of dust produced by this supernova may help explain the dust observed in young galaxies. We report far-infrared and submillimeter observations of supernova 1987A, the star whose explosion was observed on 23 February 1987 in the Large Magellanic Cloud, a galaxy located 160,000 light years away. The observations reveal the presence of a population of cold dust grains radiating with a temperature of about 17 to 23 kelvin at a rate of about 220 times the luminosity of the Sun. The… 

Dust in Supernovae and Supernova Remnants I: Formation Scenarios

Supernovae are considered as prime sources of dust in space. Observations of local supernovae over the past couple of decades have detected the presence of dust in supernova ejecta. The reddening of

Rapid formation of large dust grains in the luminous supernova 2010jl

The rapid formation of dust in the bright SN 2010jl and the wavelength-dependent extinction of this dust reveals the presence of very large grains, which resist destruction, providing the link between the early and late dust mass evolution in supernovae with dense circumstellar media.

High-Resolution Observations of Dust in SN 1987A

Abstract The dust produced by supernovae is an important topic for understanding supernova physics and the chemical evolution of galaxies. Recent ALMA observations of SN 1987A have allowed us to peer

Dust Production and Particle Acceleration in Supernova 1987A Revealed with ALMA

Supernova (SN) explosions are crucial engines driving the evolution of galaxies by shock heating gas, increasing the metallicity, creating dust, and accelerating energetic particles. In 2012 we used

Molecules and dust in the ejecta of Type II-P supernovae

Abstract We study the formation of molecules and dust clusters in the ejecta of solar metallicity, Type II-P supernovae using a chemical kinetic approach and follow the evolution of molecules and

Astrophysics: Survival of the largest

Spectrographic observations of SN 2010jl are consistent with the rapid formation of dust in its dense circumstellar medium, and the wavelength-dependent extinction of this dust points to the presence of very large grains, greater than a micrometre in diameter, that resist destruction.

Dust formation and evolution in the ejecta of core-collapse supernovae

Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter

Old supernova dust factory revealed at the Galactic center

Infrared observations of warm dust associated with a local supernova remnant reveal the dust origins for far older galaxies and suggest that supernovae may be the dominant dust-production mechanism in the dense environment of galaxies of the early universe.

The Remnant of Supernova 1987A

Although it has faded by a factor of ∼107, SN 1987A is still bright enough to be observed in almost every band of the electromagnetic spectrum. Today, the bolometric luminosity of the debris is

Dust in historical Galactic Type Ia supernova remnants with Herschel★

The origin of interstellar dust in galaxies is poorly understood, particularly the relative contributions from supernovae and the cool stellar winds of low-intermediate-mass stars. Recently, large



Far-infrared observations of thermal dust emission from supernova 1987A

INFRARED observations of supernova 1987A are important for studying both the evolution of the ejecta and its interaction with the surrounding interstellar medium. Here we report observtions of

Dust formation in early galaxies

We investigate the sources and amount of dust in early galaxies. We discuss dust nucleation in stellar atmospheres using published extended atmosphere models, stellar evolution tracks and nucleation


Two distinct scenarios for the origin of the ∼4 × 108 M☉ of dust observed in the high-redshift (z = 6.4) quasar J1148+5251 have been proposed. The first assumes that this galaxy is much younger than

Observing Supernova 1987A with the Refurbished Hubble Space Telescope

Observations with the Hubble Space Telescope, conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A, and it is found that the Lyα and Hα lines from shock emission continue to brighten, whereas their maximum velocities continue to decrease.


We present extensive observations of the radio emission from the remnant of supernova (SN) 1987A made with the Australia Telescope Compact Array (ATCA), since the first detection of the remnant in

The global gas and dust budget of the Large Magellanic Cloud: AGB stars and supernovae, and the impact on the ISM evolution

We report on an analysis of the gas and dust budget in the the interstellar medium (ISM) of the Large Magellanic Cloud (LMC). Recent observations from the Spitzer Space Telescope enable us to study

SN 1987A after 18 Years: Mid-Infrared Gemini and Spitzer Observations of the Remnant

Using the Gemini South 8 m telescope, we obtained high-resolution 11.7 and 18.3 μm mid-IR images of SN 1987A on day 6526 since the explosion. All the emission arises from the equatorial ring. Nearly

Time evolution of the line emission from the inner circumstellar ring of SN 1987A and its hot spots

Supernovae are some of the most energetic phenomena in the Universe and they have throughout history fascinated people as they appeared as new stars in the sky. Supernova (SN) 1987A exploded in the

Discovery of hard X-ray emission from supernova 1987A

We report the discovery of hard X-rays from the region of the supernova SN1987A in the Large Magellanic Cloud. The observations were made from the Mir-Kvant observatory 'Röntgen'. Hard X-rays were

The X-Ray Remnant of SN 1987A

We present high-resolution Chandra observations of the remnant of SN 1987A in the Large Magellanic Cloud. The high angular resolution of the Chandra X-Ray Observatory permits us to resolve the X-ray
