How do stars appear on the H-R diagram? On the H-R diagram, stars are not uniformly distributed. The  main-sequence stars appear in decreasing order, from hotter, more  massive blue stars to cooler, less massive r…ed stars. The stars nearest to Earth are not very bright, and thus appear at the bottom right of the H-R diagram, instead of the top of the diagram like the brightest stars.

- Main Sequence blue giants such as Rigel are located on the left-hand side of the H-R diagram. The order is O B A F G K M, and these are spectral classes based on color and tem…perature. The hottest stars burn blue/white because blue light has the shortest wavelengths and the highest temperatures.

- If you are curious to learn more about the star Sirius, please read on... About Sirius, the brightest star in the night sky Sirius is visible on the far left of the above photograph, to the left of the constellation of Orion and Comet Hale-Bopp. Intrinsically, Sirius is over 20 times brighter than our Sun and over twice as massive.

Draco (constellation) It is a blue-white giant star of magnitude 3.7, 309 light-years from Earth. The traditional name of Alpha Draconis, Thuban, means head of the serpent. There are three stars under magnitude 3 in Draco. The brighter of the three, and the brightest star in Draco, is Gamma Draconis, traditionally called Etamin or Eltanin. It is an orange giant star of magnitude 2.2, 148 light-years from Earth. The aberration of starlight was discovered in 1728 when James Bradley observed Gamma Draconis. Nearby Beta Draconis, traditionally called Rastaban, is a yellow giant star of magnitude 2.8, 362 light-years from Earth. Its name shares a meaning with Thuban, head of the serpent.

Stellar Evolutionary Tracks in the HR Diagram The HR diagrams that we studied in Lesson 4 are very useful tools for studying stellar evolution. A typical HR Diagram (e.g., the one for the stars in the cluster M55, below) plots a single point per star to represent that star's color and luminosity (or brightness) as it is observed today. So, you can consider an HR Diagram of that type to represent a snapshot of a moment in the lifetimes of the stars plotted.

Star Colors and Luminosities: The H-R Diagram Most of the things you can see in the night sky are stars: a few thousand are visible to the unaided eye. A star is a hot ball of mostly hydrogen gas; the Sun is an example of a typical, ordinary star.n some nebulae, stars form out of large clouds of gas and dust; once some stars have formed inside the cloud, their light illuminates the cloud, making it visible to us. These star formation regions are sites of emission and reflection nebulae, like the famous Orion Nebula shown in the picture on the right.

- Gienah Corvi is the right-hand star at the top of the box and one of the pointers to Spica (the other Algorab), as if Spica really needs such. Though the brightest star in the constellation, just over the second magnitude line to third (2.59), Bayer oddly gave it the Gamma designation, Alpha a fourth magnitude star beneath the right-hand side of the prominent box.

Colors and Temperatures The coolest stars emit most of their energy in the infrared and appear red, like a glowing electric stove element. The star Betelgeuse, in the constellation Orion is a good example of a red star.

- Find the Big Dipper in the sky. Follow the edge of the ladle 5 times its length up the edge of the ladle. The brightest star there is Polaris the North Star which is virtually north. Cassiopeia is a 'W' shaped constellation across the North Star from the Big Dipper. It's 'W' points right at the north star also.

- Rigel is the brightest star in the constellation Orion and a typical blue-white supergiant, Deneb is the brightest star in Cygnus and a white supergiant, Delta Cephei is the famous prototype Cepheid variable and a yellow supergiant, while Betelgeuse and Antares are red supergiants.

- So, broadly speaking, there are so many stars on the main sequence – compared to elsewhere in the H-R diagram – because stars spend much more of their lives burning hydrogen in their cores than they do producing energy in any other way!

- The Horsehead Nebula, one of the most famous dark nebulae, is located in the constellation Orion. 1  Emission nebulae are huge bright gas clouds with irregular shapes and dimensions that span many light years across. Emission nebulae are where stars are born. When stars begin to shine, they heat up the remaining gas around them and that gas starts to shine as well. One of the most famous emission nebula is M42, which is located in the constellation Orion.

Top 10 Brightest Stars in the Night Sky The Top Ten. Arcturus is the brightest star in the northern celestial hemisphere. The name of the star derives from Ancient Greek and means Guardian of the Bear or “watcher, guardian. It is a relatively close star at only 36.7 light-years (11.26 parsecs) from Earth and is a red giant about 110 times brighter than the Sun.

- Pulsating Variable Stars and the Hertzsprung-Russell Diagram . The Hertzsprung-Russell (H-R) Diagram: The H-R diagram is an important astronomical tool for understanding how stars evolve over time. Stellar evolution can not be studied by observing individual stars as most changes occur over millions and billions of years. Astrophysicists observe numerous stars at various stages in their evolutionary history to determine their changing properties and probable evolutionary tracks across the H-R diagram.

Red Giant Stars: Facts, Definition & the Future of the Sun This picture of the dramatic nebula around the bright red supergiant star Betelgeuse was created from images taken with the VISIR infrared camera on ESO’s Very Large Telescope (VLT). This structure, resembling flames emanating from the star, forms because the behemoth is shedding its material into space. Credit: ESO/P.
