Transit Search for Exoplanets around Alpha Centauri A and B with ASTERIA

Abstract: Alpha Centauri is a triple star system with two Sun-like stars, α Cen A (V = 0.01) and B (V = 1.33), and a third fainter red dwarf star, Proxima Centauri. Most current transit missions cannot produce precision photometry of α Cen A and B as their detectors saturate for these very bright stars. The Arcsecond Space Telescope Enabling Research in Astrophysics (ASTERIA) was a technology demonstration mission that successfully demonstrated two key technologies necessary for precision photometry achieving line-of-si… Show more

“…In our simulations, we assume the number of satellites in the constellation to be [0, n sat ], where the maximum number is n sat = 8. A detector concept for placing a telescope on a Small Satellite can be based off of ASTE-RIA (Arcsecond Space Telescope Enabling Research in Astrophysics) [20]. ASTERIA is a 6U CubeSat with a telescope aperture of 6.7 cm with a CMOS detector of 2592 × 2192 pixels.…”

“…We vary Φ, the space-flight instrument orbital phase to span over a range of values of δ τ and δ β . Our microlensing parallax, π E , is given by Equation (20). From [8], we make the same assumptions of the source being located in the galactic bulge at 4 kpc, lens at 8 kpc with a relative lens-source speed of 200 km/s to obtain the value of π E .…”
