This causes nuclear fusion.]]> 2016-12-08 18:39:29 UTC https://padlet.com/johanna_tirone/bqevwiltrlia/wish/142647333 How do the luminosities and lifetime of stars depend on their mass? danielle_stehle https://padlet.com/johanna_tirone/bqevwiltrlia/wish/142647453 More massive stars must also in turn be more luminous (and make more energy) in order to support their weight. This is the mass-luminosity relationship.]]> 2016-12-08 18:39:52 UTC https://padlet.com/johanna_tirone/bqevwiltrlia/wish/142647453
