The star cuddled up to UGC 12515 is the Mira-type variable
W Pegasi, so perhaps we could call UGC 12515 the Ghost of W Pegasi.
However, this pair did not rank as high as WZ Cas for the fact that the red star is actually a Mira-type variable
, pulsating with a much greater amplitude than WZ Cas and fading to as faint as 12th magnitude at minimum.
R Aquarii is, on first impression, a standard Mira-type variable
, pulsing from about magnitude 6 to 11 and back every year and three weeks.
In addition, there are no naked-eye stars nearby, except when the Mira-type variable
Chi ([chi]) Cygni is at maximum, which won't occur again until the latter half of October.
A beautiful example of contrasting star colors reappears every 15 months when T Cassiopeiae, especially red even for a Mira-type variable
, rises to its maximum brightness.
What's the second-brightest Mira-type variable
star after Mira itself?
R Draconis is a Mira-type variable
star, an unstable giant star whose outer layers periodically expand and contract.
It's a Mira-type variable
, an unstable giant star whose outer
The most intensely studied N star is CW Leonis, while the Mira-type variable
Chi Cygni is the brightest S star visible from Earth.
T Ursae Majoris, a red Mira-type variable
star, pulses from about magnitude 13.0 to 7.7 and back every eight months.
BRIGHT VEGA SHINES high overhead in September and October, and just a binocular field west of it is a Mira-type variable
star to get to know.
It seemed like any other Mira-type variable
when German asteroid hunter Karl Ludwig Harding discovered it in 1810.
