Typical of a class of stars with pulsation periods longer than 100 days.

Many stars of this kind exhibits multiple pulsation periods.

The pulsation period will be of order I", but clearly parameter dependent.

All of the pulsation periods are in the range of 4.03-4.59 hours.

In 1994 it was discovered that 35 Aquilae is a variable star with a pulsation period of just 30 minutes.

The pulsation periods of these oscillators lie between 5 and 21 minutes.

It includes a variable star with a pulsation period of around 8 hours.

There is a strong direct relationship between a Cepheid's luminosity and pulsation period.

The identified pulsation periods are 32.3, 38.5, and 44.9 days.

This is a semi-regular variable star with a single pulsation period of 20 days.
