Observational considerations are discussed for detecting echoes from flare star photospheres and from stellar or planetary companions. Synethetic spectra are used to determine optimal conditions for the recovery of echoes in flare lightcurves. The most detectable echoes are expected to appear in broadband observations of the UV continuum. Short-livedflares are ideal for resolving echoes from the flare star photosphere and may provide constraints for stellar flare models. Strong outbursts may be… 

A Framework for Planet Detection with Faint Light-curve Echoes

A stellar flare can brighten a planet in orbit around its host star, producing a light curve with a faint echo. This echo, and others from subsequent flares, can lead to the planet’s discovery,

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

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 Direct Detection and Characterization of M-dwarf Planets Using Light Echoes

Exoplanets orbiting M-dwarf stars are a prime target in the search for life in the universe. M-dwarf stars are active, with powerful flares that could adversely impact prospects for life, though

Observability of Scattered-Light Echoes around Variable Stars and Cataclysmic Events

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

A search for extrasolar planets using echoes produced in flare events

A SEARCH FOR EXTRASOLAR PLANETS USING ECHOES PRODUCED IN FLARE EVENTS A detection technique for searching for extrasolar planets using stellar flare events is explored, including a discussion of

Extra-solar planets

The discovery of the first extra-solar planet surrounding a main-sequence star was announced in 1995, based on very precise radial velocity (Doppler) measurements. A total of 34 such planets were

Searching for Unseen Planets Via Occultation and Microlensing

The fields of occultation and microlensing are linked historically. Early this century, occultation of the Sun by the Moon allowed the apparent positions of background stars projected near the limb

The history of exoplanet detection.

The early developments of the more quantitative aspects of exoplanet detection are summarized and the more relevant historical background is organized according to the observational techniques that are currently most relevant.
