Radial velocity planets de-aliased. A new, short period for Super-Earth 55 Cnc e
@article{Dawson2010RadialVP, title={Radial velocity planets de-aliased. A new, short period for Super-Earth 55 Cnc e}, author={R. Dawson and D. Fabrycky}, journal={The Astrophysical Journal}, year={2010}, volume={722}, pages={937-953} }
Radial velocity measurements of stellar reflex motion have revealed many extrasolar planets, but gaps in the observations produce aliases, spurious frequencies that are frequently confused with the planets' orbital frequencies. In the case of Gl 581 d, the distinction between an alias and the true frequency was the distinction between a frozen, dead planet and a planet possibly hospitable to life. To improve the characterization of planetary systems, we describe how aliases originate and… CONTINUE READING
