Deflating a Star Size, Again, or Two

New blog on the kid: Deflating a Star Size, Again, or Two · What Would an Astrophysicist Object, and Why Don't I Buy It? · Supernova of Kepler - 20 000 light years away? · Crab Nebula · Creation vs. Evolution: "Beams of Distant Starlight" · But of Course Astrophysics is a Science, Right ...?

Hypothesis: stars are 1 light day up (yes, I know the unit is usually not used in astronomy). This means the distance given by Heliocentrics is deflated to the distance of 1 light day.

Supposed largest mass, R136a1:

Let's say you're talking about mass. The record holder there is the star R136a1, Massey said. It's located about 160,000 light-years from Earth in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way. In diameter, this star is 30 to 40 times the size of our sun — picture a cherry next to a giant yoga ball that is more than 200 times more massive. This star is also relatively young — roughly 1 million years old compared with our sun's 4.5 billion years — and "hasn't done much cooling off or expanding," according to Massey.

160,000 light years * 365.25 days per year = 58,440,000 light days - the reduction will divide by this.
Diameter of the Sun 1,392,684 km

A) Times 30 = 41,780,520 km
B) Times 40 = 55,707,360 km
A Reduced = 714 m
B Reduced = 954 m

Supposed largest diameter, UY Scuti:

If the biggest star in the universe is the one with the largest diameter, there are a number of contenders, Massey said. At the top of that list is UY Scuti (opens in new tab). This red hypergiant's diameter is roughly 1,700 times that of the sun, according to a 2013 study published in the journal Astronomy and Astrophysics (opens in new tab). If the sun were a cherry, UY Scuti would be a 10-story-high sphere. But there's a lot of uncertainty in determining the diameter of very distant stars (UY Scuti is about 9,500 lightyears (opens in new tab) from Earth — give or take 1,000 lightyears).

10,500 light years * 365.25 days per year = 3,835,125 light days (Divider for Reduction A)
8,500 light years * 365.25 days per year = 3,104,625 light days (Divider for Reduction B)

Times 1700 = 1,183,781,400 2,367,562,800 km

Reduction A 617 km 336 m
Reduction B 762 km 592 m

But while our sun may not be the biggest star in the universe, it's certainly not the smallest, either. So, what's the smallest known star? That honor goes to EBLM J0555-57Ab, according to a 2017 study published in the journal Astronomy and Astrophysics (opens in new tab). EBLM J0555-57Ab is smaller than the planet Saturn and barely squeaks by with its star designation, the authors reported. At a lower mass, it wouldn't be able to sustain nuclear fusion at its core, and would instead be classified as a brown dwarf — a failed star.

I need more data:

EBLM J0555-57 is a triple star system approximately 670 light-years from Earth.

670 light years * 365.25 days per year = 244,717.5 light days
Smaller than Saturn? That's 116,464 km
Reduction 476 m.
