The century-old brass telescope was broken in places and long past its useful life — but it captured Lennart Lindegren's heart. Forty years ago, when Lindegren was a graduate student at the Lund ...

Michelson interferometers are used in astronomy at wavelengths from the radio to the optical for spectroscopy, for astrometry, and for synthetic imaging. The major equations giving the response of ...

So what Currie and his international team of research colleagues did was first use indirect methods of exoplanet detection — known as precision astrometry — to locate stars that could ...

BALTIMORE - A new search engine will soonturn your night sky images into powerful research data and identify thetwinkling objects in them with just the click of a button. The Astrometry ...

In a paper slated for publication April 14 in Science, Currie reports the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a ...

AbstractWe characterize the performance of the widely used least-squares estimator in astrometry in terms of a comparison with the Cramér–Rao lower variance bound. In this inference context the ...
