Incidence and survival of remnant disks around main-sequence stars
We present photometric ISO 60 and 170 um measurements, complemented by some IRAS data at 60 ${\mu\textrm{m}}$, of a sample of 84 nearby main-sequence stars of spectral class A, F, G and K in order to
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
The bolometric light curve of SN 1987A. I. Results from ESO and CTIO U to Q0 photometry
The UV, optical, and IR (UVOIR) bolometric luminosity curve of SN 1987A was derived from ESO, CTIO, and NASA Kuiper Airborne Observatory spectrophotometry for days 1-903 since outburst. It is found
Infrared aperture photometry at ESO (1983-1994) and its future use.
We describe the infrared (IR) photometric system for the single channel photometers at ESO, which have been used from 1983 until 1994. In addition to the broadband near infrared (NIR, 1 5 m)
Dust Condensation in the Ejecta of SN 1987A
Work at ESO on the formation of dust from newly synthesized elements in the ejecta of SN 1987A began in late January when blue shifts of ≃ 600 km s-1 were found for various optical emission lines in
The Mid-Infrared Instrument for the James Webb Space Telescope, III: MIRIM, The MIRI Imager
In this article, we describe the Mid-Infrared Imager Module (MIRIM), which provides broadband imaging in the 5-27 mu m wavelength range for the James Webb Space Telescope. The imager has a 0 ''.11
Infrared and X-Ray Evidence for Circumstellar Grain Destruction by the Blast Wave of Supernova 1987A
Multiwavelength observations of supernova remnant 1987A show that its morphology and luminosity are rapidly changing at X-ray, optical, infrared (IR), and radio wavelengths as the blast wave from the
Evolution and Geometry of Hot Spots in Supernova Remnant 1987A
We present ground-based near-infrared imaging and Hubble Space Telescope optical imaging and spectroscopy of the interaction between the ejecta of SN 1987A and its equatorial circumstellar ring. This
The episodic dust-maker WR 125 – II. Spectroscopy and photometry during infrared maximum
During 1992-93 the infrared flux from the Wolf-Rayet star WR 125, which formed a dust shell in 1990-91, reached a maximum. This is attributed to the continuous formation of dust in its wind until
