Star forming main sequence of galaxies
WebbWe explore the star-forming properties of late-type, low surface brightness (LSB) galaxies. The star-forming main sequence ( – ) of LSB dwarfs has a steep slope, indistinguishable from unity (1.04 ± 0.06). They form a distinct sequence from more massive spirals, which exhibit a shallower slope. The break occurs around , and can also be seen in the gas … Webb13 apr. 2024 · Most stars in the galaxy, including our Sun, are categorized as main sequence. This is a state in which nuclear fusion in the star is stable and hydrogen is converted to helium. This process releases a lot of energy that keeps the star hot and bright, and it supplies an outward pressure against the incredible mass of material that …

WebbThe star-forming main sequence ( {SFR}- {M} * ) of LSB dwarfs has a steep slope, indistinguishable from unity (1.04 ± 0.06). They form a distinct sequence from more massive spirals, which exhibit a shallower slope. The break occurs around {M} * ≈ {10} 10 {M} ⊙ , and can also be seen in the gas mass—stellar mass plane. WebbWe investigate the mean star formation rates (SFRs) in the host galaxies of similar to 3000 optically selected quasi-stellar objects (QSOs) from the Sloan Digital Sky Survey within the Herschel-ATLAS fields, and a radio-luminous subsample covering the redshift range of z = 0.2-2.5. Using Wide-field Infrared Survey Explorer (WISE) and Herschel photometry (12 …
