Star In A Box

Star In A Box Made by: Mika Lorin A. Padilla Grade 9 - Genesis

Guide Questions: 1. How are the size and color of stars affected as the star’s age? They give out hydrogen to burn, lessening the quantity of energy they vent. Consequently, older ones look redder, while younger stars can look bluer. Warmer stars are orange or yellow, and exceedingly hot stars are blue or blue-white. Immense stars produce more energy, so their exteriors are hotter. These stars tend toward bluish-white. That is why a star's color can tell us the star's age.



Guide Questions: 2. How does the temperature change as the star evolves through time? The fusion of hydrogen to form helium changes the inside structure of a star, which results in changes in its temperature, luminosity, and radius. The core will then decrease due to gravity. As a result, the temperature inside the core can increase and activate more fusion.



Guide Questions: 3. What happens to the brightness of the stars as they age? Many factors affect the brightness of a star, and these count surface area, mass, evolutionary stage, temperature, and distance. As I observed, a higher-mass star may have more matter, but it burns through it faster due to higher core temperatures caused by higher gravity. It vents blue light, then it becomes red supergiant it vents red light. Meanwhile, It becomes a supernova and bright light is vented. Finally, it becomes a black hole. For lower mass star. Like our Sun it emits yellow light. Then it becomes a red giant and vents red light.



Guide Questions: 4. What happens to a stars mass as they age? As I’ve noticed while investigating the “star in a box”, stars with higher mass have shorter lifespans. While low mass star spend its core hydrogen and converts it into helium.



Guide Questions: 5. Which stage in In the H-R diagram, the the H-R diagram do stars spend most of stars spend most their lifetime is in the of their lifetime? main sequence phase. This is the point where nuclear fusion is getting hydrogen into helium. The light pressure of this energy balances out the star's gravity that causes the star to steady.
