A main sequence star is a star that is not surprisingly on "the main sequence". This is the period when a star is fusing hydrogen into helium.
Most stars you see in the night sky are main sequence stars.
red giant
None of those is a main sequence star.
It will become a red giant.
Two types of stars that can form from nebula are main sequence stars, like our Sun, and giant stars, which are larger and brighter than main sequence stars. Main sequence stars fuse hydrogen into helium in their cores, while giant stars have expanded and evolved from the main sequence phase.
Yes, a red giant is generally much brighter than a main sequence star of the same temperature. While main sequence stars like our Sun fuse hydrogen into helium in their cores, red giants have exhausted their hydrogen and expanded, leading to increased luminosity due to their larger size and surface area. This increase in brightness can be several hundred to thousands of times greater than that of a typical main sequence star.
main sequence,giant then nebula
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
After the main sequence, a star becomes a red giant.
No. Red giants are not on the main sequence.
red giant
The correct order of these stellar evolutionary stages is main sequence, red giant, white dwarf. A star begins its life on the main sequence where it fuses hydrogen into helium. As it runs out of fuel, it expands into a red giant before shedding its outer layers and collapsing into a white dwarf.
Main sequence stars, like the Sun, fuse hydrogen into helium in their cores, maintaining a stable balance between gravitational collapse and nuclear fusion. In contrast, red giant stars have exhausted hydrogen in their cores and have expanded significantly, fusing helium and other heavier elements in shells around the core. This results in a cooler surface temperature, giving red giants their characteristic reddish hue, while main sequence stars typically have a hotter, brighter appearance. Additionally, red giants are much larger and more luminous than their main sequence counterparts.
i don't think so
Main sequence star: hydrogen-1. Red giants: helium-4.
The main difference between communication diagrams and sequence diagrams is that sequence diagrams are good at showing sequential logic but not that good at giving you a "big picture view" whereas communication diagrams are the exact opposite
None of those is a main sequence star.
Red giant is the largest and the brightest.
