I don't think the title is really accurate- it doesn't emit radio signals every 8 minutes, it emits constantly, but emits along an axis that periodically aligns with our viewing cone.
Yes but repeated evenly spaced pulses are special and limited to a special subset of stars caller pulsars. The sun is mostly wideband radio noise where the article is talking about distinct regular pulses which are rarer.
If you have satellite TV you already have a solar radiotelescope.
Measure the voltage on the AGC line in the tuner and you'll see a peak as the sun passes the azimuth of the dish. That's it picking up 10GHz solar radiation, and turning its gain down to compensate for the background noise.
I didn't know that there was a whole slew of these red and white dwarfs orbiting other stars, which I think must make it extra unlikely for there to be habitable planets in the same system, the process of one star capturing another is going to realy wreck havock with any original planets,
and any surviving lifeform to get past the am radio phase of technological development

Make it random, at least receivers would have a harder time identifying intentions
What wait, 8mn is a long period?
I checked the fastest pulsar observed rotates and “emits” at 716Hz! :shock:
That’s ~70.000km/s on the equator given its ~30km diameter :shock: :shock:
