Sky Candy #3 — Challenge list of 45 O-runaway stars

Our astronomy observer’s instinct is to seek objects faint, fuzzy, and far away. Yet there is a remarkable observing challenge right on our doorsteps that requires no more investment than a pair of binoculars — O runaway stars. These are massive, furiously hot Class-O stars twenty or more times the mass of the sun that are unaccountably roaming the skies with no attachment to anything.

The third article in the newly inaugurated Sky Candy series is "Riding with the Valkyries — an O-Runaway Star Observer's Guide." It is especially suited for young enthusiasts with a pair of binoculars who can't see most of the Messier list, but who also want a challenge list of their very own to take pride in honing their skills.


How did O runaways get to be such wandering loners? Their tales reveal galactic life styles that we cannot imagine simply by looking at them. They are speeding along in near-solitude in parts of the Galaxy where they should not be. How did such hugely massive objects acquire velocities of 40 or more kilometers a second?


Yet for all their fabulous physics, they are easy to find in a pair of binoculars. The seven-page Observer’s Guide at the end of this article lists 45 O runaways we can spot naked eye or with inexpensive binoculars. It is an ideal challenge list for newcomers fascinated with the lore and beauty of the night sky.



Good hunting! =Doug Bullis, South Africa
