8. http://www.mso.anu.edu.au/seminars/abstracts/20151022-1100.html
Thanks to numerous ground and space-based surveys, we are now aware of over 1800 planets orbiting other stars, with another nearly 5000 candidates from the Kepler Mission awaiting confirmation. ... The answer to this question lies in the study of young planets and their formation environments. In this talk I will show how high-precision time series data from space telescopes is beginning to illuminate the conditions surrounding planet formation and the star-disk connection. ...

If the star drifts northward, your scope is west of the pole. ... Remember that as your adjustments get you closer to the pole, the star will drift slower and you must wait longer to detect a north-south drift. If the star drifts south, you are east of the pole and you must turn the mount towards the west. ... www.astronomy.net . ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

11. The Path of the Sun, the Ecliptic
The apparent path of the Sun across the sky. ... The path of the Sun across the celestial sphere is very close to that of the planets and the moon. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

16. Source Selection
... The stars examined here were primarily culled from two lists of X--ray sources in Orion. ... The second region is two degrees in extent east--west and ten degrees north--south with Orionis being near the northern edge. ... In the end, two main regions were chosen for monitoring: stars near Orionis and stars northwest of the belt of Orion. ...

20. BG1-3 catalogs
... The IAUname was INFERRED from the coordinates using the same procedure as in the original publication (i.e. the last digit in declination is the NEAREST tenths of degrees, rather than rounding to the NEXT LOWER tenth of degrees). Note that this procedure is against IAU recommendations, but according to a stronger IAU recommendation (saying that published names should never be changed) I retained the incorrect original naming system in the present electronic version of the catalog. ...
