Here we prop ...Continue Reading

These objects have either poor or no existing parallax measurements. FGS parallax det ...Continue Reading

Concordance cosmogony makes that prediction. It is, however, a prediction of extrasolar planetary system architecture as yet untested by direct observation for main sequence stars other than the Sun. To provide ...Continue Reading

That measurement resulted in an absolute magnitude, M{V}= 0.61+/-0.11, a useful result, judged by the over ten refereed citations each year since. It is, however, unsatis ...Continue Reading
