The writer suggested that the angular momentum of the stars was related to the original cloud that collapsed to form them and not the galaxy angular momentum. ... As I understand the answer to 902372110.as, if the stars orbit is not related to the galaxy spin, then I would expect the stars to orbit the galaxy at a multitude of random orbits and no disk to form. ...

... The very demanding goal of 50 milliarcseconds root-mean-square (mas RMS) for the astrometric precision of the Sloan Digital Sky Survey implies that focus and collimation motions of the secondary must be very smooth.

... The QBO period is equal to a linear combination of the frequencies corresponding to the doubled periods: of the tidal year (0.97 year ), of the regression of nodes (18.6 years ), and of the motion of perigee ( 8.85 years ) of the Earth's monthly orbit : 1 2 1 1 1 0.97 18.61 8.85 1 2.3 yr (1) In other words, the quasi-biennial oscillation of the wind direction in the equatorial stratosphere is a combined oscillation ...

... This paper discuss a polynomial approximation to T for the range of 1620 to 2000 AD published by Jean Meeus and Larry Simons and gives a modified version of this approximation which is much more accurate. ... For this purpose Jean Meeus and Larry Simons published a paper in 2000, which gives a set of polynomial approximation of T for the range of years 1620 to 2000 (Meeus 2000). ...
