What is the color of Matar?
Eta Pegasi (Matar) is a star in the constellation Pegasus.It has a spectral type of G2 so it has a colour of yellow.Matar has the same spectral class as our Sun
If humans and pandas belong to the same class then they must also belong to the same?
phylum
How old is Alioth?
That is an impossible question to answer. All stars are different and to deduce the age of a star is very difficult. Based on it's spectral type of A, it is likely to be the same age as other stars, so it's about 2-3 × 108 years old. (200 Million years). Our Sun is about 5 billion years old.
How was helium identified on the sun with a spectroscope?
Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.
Does Every element and compound in nature have a unique set of spectral lines?
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
What nearby star is in the same spectral class as the sun?
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun
What is a Subdwarf star?
A star with luminosity class VI under the Yerkes Spectral Classification System. They have luminosity 1.5 to 2 magnitudes lower than main-sequence stars of the same spectral type.
What is the color of Matar?
Eta Pegasi (Matar) is a star in the constellation Pegasus.It has a spectral type of G2 so it has a colour of yellow.Matar has the same spectral class as our Sun
What is some information on blue stars?
Blue stars exhibit a moderate increase in size and luminosity compared to main sequence stars of the same mass or temperature, and are hot enough to be called blue, meaning spectral class O, B, and sometimes early A. They have temperatures from around 10,000K upwards.
What is the proof that the sun is a star?
It is hot and luminous. It has the same spectral qualities of other stars. It's chemical composition is the same as other stars. It's a star - We call our star the Sun.
Why are distant stars redder than nearby stars of the same spectral type?
The reddest stars are the stars that are considered the coolest. Blue light is more effectively scattered than Red light. This is called ``interstellar reddening".
When astronomers look for evidence of hydrogen gas in the spectra of the Sun the planets and nearby stars the positions of the spectral features or lines due to hydrogen are different or the same?
They are the same.
You observe the same spectral line in two stars that are identical in every way except that one rotates faster than the other How does the spectral line differ between the two?
The line in the faster rotating star is broader.
What are stars that are similar to the sun called?
Stars similar to our Sun have a stellar class of G2V - Alpha Centauri A has the same class as our Sun
What type of star is Acrux?
Acrux (Alpha Crucis) is not a single star, what we know of it makes two stars visible (A1 and A2). Both stars are Class B, pushing Class O (blue-white to blue). A1 is a B0.5IV (B=blue-white class, 0.5=temperature range {0 being hottest, 9 being coolest}, IV puts A1 in the sub-giant range. A2 is a B1V, the same B class, however it is cooler than A1 and much smaller, V-making it a dwarf.So, B is the color from the Harvard Spectral Classification. The number is a subdivision of the Harvard Spectral Classification and addresses temperature and luminosity. The Roman numeral is the Yerkes Spectral Classification and addresses the size and luminosity (broken into 8 divisions from hypergiants to white dwarfs).
Two species belonging to the same class must also belong to the same?
Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.
What condition a function must specify in order to create objects of a class?
The object must have same name as that of class name.
