Asteroseismology of red giants in the globular cluster 47 Tuc using the HST

Dennis Stello, Ronald L. Gilliland, Timothy R. Bedding

HST data detect solar-like oscillations in two red giants of 47 Tuc, giving masses of 0.78 and 0.94 solar masses and implying 0.16 solar masses lost on the upper RGB.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

From the seismic signal, we measure the stellar masses to be 0.78±0.13 M⊙ (HB) and 0.94±0.15 M⊙ (RGB), and hence an inferred integrated mass loss along the upper RGB of 0.16±0.20 M⊙.

C2weakest assumption

The detected signals are solar-like oscillations whose frequencies can be converted to mass via standard scaling relations calibrated on field stars; the abstract provides no details on signal-to-noise, mode identification, or possible systematic offsets in the scaling relations for cluster stars.

C3one line summary

First detection of solar-like oscillations in red giants of 47 Tuc gives masses of 0.78 and 0.94 solar masses and an inferred RGB mass loss of 0.16 solar masses with large uncertainties.
