Seismology of triple-mode classical Cepheids of the Large Magellanic Cloud
Seismology of triple-mode classical Cepheids of the Large Magellanic Cloud
We interpret the three periods detected in OGLE LMC Cepheids SC3–360128 and SC5–338399 as corresponding to the first three overtones of radial pulsations. This interpretation imposes stringent constraints on parameters of the stars and on their evolutionary status, which could only be the first crossing of the instability strip. Evolutionary …
