It means that it is the same size and surface temperature as our sun.
It isn't. The sun is a star and there are others that are similar in size and temperature.
Alpha Centauri is the nearest star that we can see and it is almost the same size and age as the Sun.
The luminosity of a star is related to its surface temperature and size. Hotter stars with larger surface areas tend to have higher luminosities, while cooler stars with smaller surface areas have lower luminosities.
To find an Earth-like planet around another star, scientists search for planets that orbit in the "habitable zone" where conditions are just right for liquid water to exist on the surface. They use telescopes to detect the planet's size, orbit, and composition, looking for similarities to Earth such as a rocky surface and the presence of water. Host stars are also studied to determine if they are similar to our Sun in age, size, and composition.
The Sun is a mid-sized, average yellow star in the Milky Way galaxy. It is classified as a G-type main-sequence star, with a surface temperature of around 5,500 degrees Celsius. Its luminosity and size place it comfortably within the range of other similar stars in our galaxy.

There are huge (several times the size of the earth) storms on the surface of the Sun, sometimes these cause gigantic flares to expand out from the surface of the star into space. These "flares" are said to "erupt".
You find its size.
There are 2 main factors: the size of the star and its surface temperature. A larger size means a larger surface area to emit light. A higher surface temperature increases the energy emitted. Seen from Earth, the brightness of a star depends on how far away the star is as well as its actual luminosity.
When a star collapses to half its size, its gravitational field at the surface increases. This is because the gravitational force is directly proportional to the mass of the star and inversely proportional to the square of the distance from the center of the object. As the star collapses, its mass remains the same but the distance to its center decreases, leading to a stronger gravitational field at its surface.
No. I assume you mean the star's diameter. The area is proportional to the square of the area - so the bigger the star, the brighter it will be - other things being equal. However, the star's surface temperature also affects its brightness.

The surface temperature of the Pollux star is 4,500 K
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
