A.
1912 paper on periods of 25 Cepheid variables in the Small Magellanic Cloud
The 1912 paper on periods of 25 Cepheid variables in the Small Magellanic Cloud is Henrietta Swan Leavitt’s landmark work that revealed the period–luminosity relationship of Cepheid variable stars, providing a crucial tool for measuring cosmic distances.
-
B.
Harvard variable star catalogues
chosen
The Harvard variable star catalogues are pioneering astronomical compilations that systematically recorded and classified variable stars, forming a foundational resource for stellar variability research.
-
C.
RR Lyrae variable stars
RR Lyrae variable stars are old, low-mass pulsating stars used as standard candles to measure distances within the Milky Way and nearby galaxies.
-
D.
Edwin Hubble’s 1923–1924 papers on Cepheids in Andromeda
Edwin Hubble’s 1923–1924 papers on Cepheids in Andromeda are landmark astronomical studies that demonstrated Andromeda is a separate galaxy beyond the Milky Way, fundamentally expanding the known scale of the universe.
-
E.
Henrietta Swan Leavitt
Henrietta Swan Leavitt was an American astronomer whose discovery of the period–luminosity relationship of Cepheid variable stars provided the key to measuring cosmic distances and revolutionized our understanding of the scale of the universe.
