Nearby single Stars Below is a list of nearby single stars (with no companian stars). Only stars visible on Mt. Hopkins are listed. The estimated RV uncertainty is calculated from the numbers in Butler's paper, taking into account the difference of the telescope diameter. I also assumed the integration time = 10 minutes. Several factors were not included: 1. Butler uses the spectral band of 500 nm - 600 nm. We may use different bands with different bandwidth. The spectral features and the spectral density of the photon flux are different. Those factors, however, are temperature dependent. 2. I assumed that we are photon shot noise limited. 3. The resolving power (R) of Hires is 70,000 and the R of TRES is 40,000. Click on the name of the stars to see when the stars are visible on Mt. Hopkins. See also Stars with known exoplanets.
