Tour of Visually Colourful Stars
      #5380508 - 08/22/12 05:26 AM

hi,

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:


HIP 100155


Albireo


T Lyrae


U Cygni


AX Cygni


RS Cygni


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!

Very nice project that should keep your enthousiasm at a high level. These are a beautiful set of sketches. I wish I could see them (your sketches) at a higher magnification.

Very fine work starquake!

Ferenc,

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

Sorry for that.

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

This is a very nice series. Wonderful idea. We do something similar in a non-sketch form as we run new observers through a few stars, so they begin to appreciate how they are unique visually.

Two more carbon stars which come to mind; V Aql and S Cep. The latter has a large range of variability, and I don't know its current magnitude, not having observed it for more than a year.

Thanks all for your comments, and especially thank you Glenn for the hints, I'll check these stars as soon as possible, especially now that Cepheus is in a fine position on my sky.

I've just added two more colorful sketches to the collection:


WZ Cas


Mu Cephei

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.

Unfortunately we had a terribly cloudy period behind us, so I had a very limited observing time. So I only have two more stars to add to the list, but I hope things will get better now.


Almach (Gamma Andromedae)


UU Aurigae

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.

Ah... Fantastic and very interesting work, Ferenc. I'm glad to see how passionate you are about stars with obvious colour because this is something that is often neglected. Keep up the good work!

Thank you all for your compliments.

Here's one more from this evening:


R Leonis

A nice bright orange variable star.

And after a little break, here are some more colorful beauties:


V CrB

Deep red with an orange hue and an uneasy location.


RR Her

Bright orange, a bit of a disappointment on the other hand.


U Lyr

Faint, deep red color. Very spectacular.


Ras Algethi

The brightest star of Hercules. Nice color contrasting binary, with a golden main component and a faint bluish companion.


BF Sge

Faint, orange/white color.


X Sge

Orange. Sort of.


X Cnc

Very bright and very orange star in Cancer.


T Cnc

A much fainter but much redder star in Cancer.

Thank you all for the kind words!

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.

Ferenc, I'm sorry to have missed this. It's quite a beautiful study of colors. I am always impressed with the stars that show distinct color, but admittedly do I seldom seek them out. When I look at your sketches I feel a strong desire to get out and find some deep red carbons and colorful contrasting doubles. Very nice work!

Only one more to add this time:



STF 1657 or 24 COM

Very nice color-contrasting binary.

A very beautiful set of colorful sketches Ferenc! I am very impressed with the doubles. You do a such an accurate job of star placement. Well done!

Imagine the way light and shadows would differ on planets or moons of these systems.
