Astrometric detection of rocky exoplanets from inexpensive space platforms

Peter G. Tuthill, George Ayad, Donald G. Dansereau +18

The detection of orbiting exoplanets by way of astrometric monitoring of the host star to reveal gravitationally induced reflex motion requires extreme precision and measurement st…

Astrometric Methods for Detecting Exomoons Orbiting Imaged Exoplanets: Prospects for Detecting Moons Orbiting a Giant Planet in Centauri A's Habitable Zone

Kevin Wagner, Ewan Douglas, Steve Ertel +5

Nearby giant exoplanets offer an opportunity to search for moons (exomoons) orbiting them. Here, we present a simulation framework for investigating the possibilities of detecting…

MeerKAT observations of Procyon at 815.5 MHz

Ian Heywood, Andrew P. V. Siemion, Daniel Czech +5

We have conducted observations of the nearby (11.46 ly) star system Procyon, using MeerKAT's UHF (544-1087 MHz) receivers. We produce full-Stokes time and frequency integrated cont…
