The blinking star

Post by brian livesey »

A "blinking" star has been discovered by astrophysicists in the central part of the galaxy that lies more than 25,000 Lys away. The star, catalogued as VVV-WIT-08, could be the first of a new class of "blinking giant" binary stars consisting of a star100 times the mass of the Sun that is eclipsed every few decades by a stellar companion.
Many stars change their luminosity over time, but its a rarity for a star to become fainter over months then brighten again. The study is published in the Monthly Notices of the Royal Astronomical Society.

Huh? Isn't that what most Mira variables do?

Mira is a pulsating variable, not an eclipsing binary.

As astronomers have a rough idea of the size and shape of the Milky Way’s much remains unknown: They can’t see the full structure of our home galaxy because Earth is inside it.
That is why the new findings are so important to be spotlighted.
Another is a finding a ‘break’ in one of the Milky Way’s spiral arms, which is also an ‘anomaly’ in our common understanding in the structure/
The first time that a structure of the Milky Way's arms is found to be standing out the constructed model from the previous measurements, observations and calculations.
Reminding of many uncertainties about the large-scale structure of the Milky Way and possible much more. A small piece that with further examination and exploration can show more about our galaxy. And really a good point of directly taking advantage for understanding the phenomena of the movement taking place within the spiral arms for understanding of the movement taking place within the spiral arms.
Another outstanding finding, that might not look like a big deal without understanding the details.
