Follow-up photometry, spectroscopy, and trigonometric parallax have been obtained in an effort to determine the fundamental parameters of each component of this system. The binary has a mass ratio of ...

Abstract: The common practice in luminosity calibration of sample truncation according to relative parallax error λ can lead to bias with indirect methods such as ...

An analytical consideration of the distance-dependent bias, previously studied in extragalactic astronomy, is given in terms of the trigonometric parallax. In a quantitative treatment of the ...

LSST’s trigonometric parallax measurements for low-mass stars near the hydrogen-burning limit will map stellar populations driving chemical enrichment, contributing to models of Galactic habitability.
