Detection Limits from the McDonald Observatory Planet Search Program
Open accessAbstract
Based on the long-term radial velocity surveys carried out with the McDonald Observatory 2.7 m Harlan J. Smith Telescope from 1988 to the present, we derive upper limits to long-period giant planet companions for 31 nearby stars. Data from three phases of the McDonald Observatory 2.7 m planet-search program have been merged together, and for 17 objects data from the pioneering Canada-France-Hawaii Telescope radial velocity program have also been included in the companion-limits determination. For those 17 objects, the baseline of observations is in excess of 23 yr, enabling the detection or exclusion of giant planets in orbits beyond 8 AU. We also consider the possibility of eccentric orbits in our computations. At an orbital separation of 5.2 AU, we can exclude on average planets of M sin i ≳ M J ( e = 0) and M sin i ≳ M J ( e = 0.6) for 25 of the 31 stars in this survey. However, we are not yet able to rule out "true Jupiters," i.e., planets of M sin i ∼ 1 M J in 5.2 AU orbits. These limits are of interest for the Space Interferometry Mission , Terrestrial Planet Finder , and Darwin missions, which will search for terrestrial planets orbiting nearby stars, many of which are included in this work.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
