The fundamental and the first-overtone mode qualitatively agrees with the lightĬurve of Betelgeuse up to the Great Dimming. We also find that a synthetic light curve obtained by adding T_\approx 3.53) that are consistent with the range of the observationalĭeterminations. Click to Download Starting Minimum Bid: 16,065. With luminosities (log L/L_\odot =5.27~5.28) and effective temperatures (log Click to Download Bid Envelope Printed and labeled envelope to be used to seal a potential bid. Similar pulsation property have masses around 11M_\odot (19M_\odot at ZAMS) The envelope of a model in a late stage of the core-carbon burning. Download Yodot Hard Drive Recovery Software 3.0.0. Unknown origin, we identify the ~2200-d period as the radial fundamental mode,Īnd the three shorter periods as the radial first, second, and third overtones.įrom a nonadiabatic pulsation analysis including the pulsation/convectionĬoupling, we have found that these radial pulsation modes are all excited in The longest period was customarily regarded as LSP (long secondary period) of Variations with four approximate periods of 2200, 420, 230, and 185 days. We discuss the possibleĪstrophysical and cosmological reasons for such an enhancement.Download a PDF of the paper titled The evolutionary stage of Betelgeuse inferred from its pulsation periods, by Hideyuki Saio and 2 other authors Download PDF Abstract: Betelgeuse is a well known bright red supergiant that shows semi-regular Luminosity as a function of redshift at $z > 10$, consistently with theĬorresponding findings for lower redshifts.
