Scattered-light echoes from variable and cataclysmic stars offer one of the most effective means to probe the structure and composition of circumstellar and interstellar media. I build a simple model of light-echo surface brightness by considering the source spectrum and the dust density, geometry, and scattering efficiency. I use this model to investigate whether echoes should be observable around short and long-period giants, cataclysmic variables, and supernovae. Only supernovae are expected… 


We present multiple-epoch measurements of the size and surface brightness of the light echoes from supernova (SN) 2014J in the nearby starburst galaxy M82. Hubble Space Telescope (HST) ACS/WFC images

Light Echoes of Transients and Variables in the Local Universe

Abstract Astronomical light echoes, the time-dependent light scattered by dust in the vicinity of varying objects, have been recognized for over a century. Initially, their utility was thought to be


We have discovered a luminous light echo around the normal Type II-Plateau Supernova (SN) 2012aw in Messier 95 (M95; NGC 3351), detected in images obtained approximately two years after explosion

Light echoes from ancient supernovae in the Large Magellanic Cloud

Three faint variable-surface-brightness complexes with high apparent proper motions pointing back to three of the six smallest (and probably youngest) previously catalogued supernova remnants in the Large Magellanic Cloud, which are believed to have been thermonuclear (type Ia) supernovae.

Stellar Echo Imaging of Exoplanets

All stars exhibit intensity fluctuations over several timescales, from nanoseconds to years. These intensity fluctuations echo off bodies and structures in the star system. We posit that it is

The Light Echo around Supernova 2003gd in Messier 74

We confirm the discovery of a light echo around the Type II‐plateau supernova 2003gd in Messier 74 (NGC 628), seen in images obtained with the High Resolution Channel of the Advanced Camera for


We report optical and mid-infrared photometry of SN 1980K between 2004 and 2010, which shows slow monotonic fading consistent with previous spectroscopic and photometric observations made 8–17 yr

A Light Echo from Type Ia SN 1995E?

We identify a light echo candidate from Hubble Space Telescope (HST) imaging of NGC 2441, the host galaxy of the Type Ia supernova 1995E. From the echo's angular size and the estimated distance to

Seeking Echoes of Circumstellar Disks in Kepler Light Curves

Light echoes of flares on active stars offer the opportunity for direct detection of circumstellar dust. We revisit the problem of identifying faint echoes in postflare light curves, focusing on

Observation of light echoes around very young stars

Aims. The goal of the paper is to present new results on light echoes from young stellar objects. Methods. Broad band CCD images were obtained over three months at one-to-two week intervals for the



Light Echo Detection of Circumstellar Disks around Flaring Stars

Abstract Light echoes can be used to detect and characterize disks around flaring stars. Such disks are thought to be a hallmark of planet formation but are very difficult to detect by ordinary

Can Light Echoes Account for the Slow Decay of Type IIn Supernovae?

The spectra of Type IIn supernovae indicate the presence of a preexisting slow, dense circumstellar wind (CSW). If the CSW extends sufficiently far from the progenitor star, then dust formation

Circumstellar infrared and scattered light echoes from SN 1987A

The observed light curve and temperature evolution and the theoretically predicted initial UV burst of SN 1987A are used to construct models for the IR echo and scattered-light echo arising from

Evolution of the Light Echo of SN 1991T

Schmidt et al. presented strong evidence (photometry and spectroscopy) that the late time optical emission of SN 1991T in the Virgo spiral NGC 4527 is caused by a light echo. Here, we present

Prospects for detecting light echoes of galactic supernovae by wide-angle polarimetry

We propose to use a global (wide-angle, of the order of several degrees) distribution of linearly polarized emission over the sky to detect light echoes of historical supernovae exploded in our

A Scattered Light Echo around SN 1993J in M81

A light echo around SN 1993J was observed 8.2 yr after explosion by a Hubble Space Telescope Wide Field Planetary Camera 2 observation, adding to the small family of supernovae with light echoes. The

A search for candidate light echoes: Photometry of supernova environments

Supernova (SN) light echoes could be a powerful tool for determining distances to galaxies geometrically, Sparks (1994). In this paper we present CCD photometry of the environments of 64 historical

Multiwavelength analyses of the extraordinary nova LMC 1991

LMC 91 was a very fast, classical nova and the brightest nova ever observed in the Large Magellanic Cloud. It was extensively observed during both its early optically thick and its nebular evolution

Multiple Light Echoes from SN 1993J

Using the technique of point-spread function-matched image subtraction, we have analyzed archival Hubble Space Telescope (HST) Wide Field Planetary Camera 2 data to reveal details of at least two

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
