pulsars (neutron stars) or Cepheid variables.
Pulsars are very rapidly rotating former stars that have a "bright spot"
(bright in the radio range, that is). This spot is not aimed directly at
Earth, but rather rotates in and out of our direction. So it effectively
generates pulses that we see. They rotate so rapidly that the pulse rate
ranges from a few milliseconds to a few seconds. So for these, the pulse
rate corresponds exactly to their rotation rate.
Cepheid variables are large stars that pulse radially (they actually
expand and contract), but their periods are measured in days. As in
anywhere from one day to 50 days. And the longer their period, the
brighter the star. Not the apparent magnitude, but the absolute
magnitude. Knowing their absolute magnitude, we can tell how far away
the star is. (This is an extremely important point, since Cepheids are
bright enough we can see them in nearby galaxies. Thus we can tell how
far away those galaxies are.)
Anyway, I figured it could be either, but the "pulses per second" in the
question made me think you meant pulsars.
Another poorly phrased aspect of the question is that it implies that
this relationship applies to all stars, whereas both pulsars and
Cepheids are a very small fraction of the stars we see.

"Calvin":

>> I don't believe rotational speed is correct but feel free to correct me.
Dan Tilque:
brightness because I guessed "star pulse" was an error for "star" and
the "pulses per second" being counted were being generated within the
photometer and not anywhere else.

Mmm, no.

That's true, but the question did refer to a photometer, indicating
that we were talking about light, not radio waves. Most pulsars do not
a visible flashing light. On another point, pulsars typically have a
rotation rate on the order of once per second, so "pulses per second"
doesn't fit.

So that certainly didn't fit with "pulses per second" either.

But it wasn't ever about pulsars and Cepheids; you just assumed it was.

It certainly is. "A star pulse" doesn't mean anything. I answered
brightness because I guessed "star pulse" was an error for "star" and
the "pulses per second" being counted were being generated within the
photometer and not anywhere else.

Based on Calvin's obvious poor knowledge of astronomy, I figured he

pulsars were on the order of one hertz (once per second), astronomers
still would want to measure them at a significantly higher rate than that.

rate for all stars. There is no such property, not even brightness.
There are two properties that are proportional to pulse rate for two
types of stars. I assumed he heard about one or the other and composed a
garbled question about it.

Having considered the various follow-up posts I've decided to let the original scores stand. Despite the question's documented shortcomings, I don't believe that only considering a small subset such as pulsars is a reasonable interpretation.
