Tour of Visually Colourful Stars
Posted 22 August 2012 - 04:26 AM
just recently I've decided to start a new project, mainly to keep my "astro-mood" high. one night I've introduced WZ Cas, a nice deeply red star with a bluish companion to my friend and she showed me RS Cyg. I was thinking that there maybe even more spectacular stars like these and that's how my colour-fever started.
so I've started to collect information and catalogues of stars that were REALLY colourful visually: variable stars, red giants, carbon stars, binaries with a nicely contrasting companion or simply stars with a remarkable colour.
here's the first bucket of stars I've "catalogued", currently all of them are in a fine position on the sky for the Northern hemisphere observers:
WDS H 4 114
for larger images and detailed observation logs for these objects, please visit my TVICS page: here it is
if you know any other stars you think I should visit at this time of the year or later, please let me know. sketches are also welcome, feel free to hijack this thread!
thank you and clear skies!

Nice capture of HIP 100155, Albireo, T Lyrae, U Cygni, AX Cygni RS Cygni & WDS H 4114 .

Very fine work starquake!

@JeanB: you can see the larger images on the page I've linked at the bottom of the original post. once there, click on any thumbnail to get the full size sketch. good luck!

These are all beauties. U Cyg gets just as red as T Lyr in your fine sketches when it nears minimum magnitude.

Sorry for that.
Imagine! I found them already gorgeous as they look. They are even more awesome now!!!

I've just added two more colorful sketches to the collection:
WZ Cas is my all time favorite, it's really like a small-scale Albireo with its contrasting blue companion, and Mu Cephei (or Herschel's Garnet Star) is a famous supergiant and superluminous star.

Almach (Gamma Andromedae)
Almach is a very nice colour contrasting binary with large difference in the brightness of its components. UU Aurigae is a variable star with a very nice orange/red colour. Both very bright, so easy target for smaller scopes too.

Here's one more from this evening:
A nice bright orange variable star.

Deep red with an orange hue and an uneasy location.
Bright orange, a bit of a disappointment on the other hand.
Faint, deep red color. Very spectacular.
The brightest star of Hercules. Nice color contrasting binary, with a golden main component and a faint bluish companion.
Faint, orange/white color.
Orange. Sort of.
Very bright and very orange star in Cancer.
A much fainter but much redder star in Cancer.

Some conclusions that I have sofar:
- just because a star is a carbon star, it doesn't necessarily mean that it's beautiful red visually.
- the nicest color-contrasting binaries are not carbon stars
- big difference in brightness of a binary's members helps seeing a color contrast
- just because a star is so vivid in color in a planetarium program, it doesn't necessarily mean that it will be colorful visually.
- ruining your dark adaptation helps seeing colors
- sometimes increasing your magnification helps
- sometimes increasing your magnification makes things worse
- stellar spectra is a good tool to find colorful stars
- stellar spectra can be very misleading
Final conclusion: believe in what you see, and not in data and catalogues.
