The majority of thick disk stars likely formed during/after the merger with Gaia-Enceladus and not before.
“As Gallart et al. (2019) showed, the majority of the thick disk stars likely formed during/after the merger with Gaia-Enceladus and not before.”
From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Gallart et al. (2019)
The age-distribution passage (p. 2) says 50% of thick-disc stars had formed by 10.5 billion years ago; the paper dates the Gaia-Enceladus merger to about 10 billion years ago (p. 3). Thus at least half had formed before the merger, contrary to the claim that the majority formed during or after it. The paper does say thick-disc star formation continued after the merger. (LLM, conf=0.88)
Checked by a reasoning model — may be wrong.
Experimental — accuracy not yet measuredThe Gaia-Enceladus merger had a mass ratio of ∼4:1.
“2018) suggest a mass ratio of ∼4:1 for the merger (which has been confirmed by Gallart et al. 2019) on the basis of the estimated stellar mass of Gaia-Enceladus, the expected stellar mass-to-halo mass ratio for objects of this size, and the assumption that a 10 10 M ࣻ thick disk stellar mass is present at the time.”
From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Gallart et al. 2019
Gallart et al. estimate a total mass ratio of around 4:1 (p. 3), supporting the cited figure. They also stress that the underlying stellar-mass ratio remains quite uncertain, so describing the 4:1 ratio as confirmed overstates their conclusion. (LLM, conf=0.86)
Experimental — accuracy not yet measuredThe evidence supports a scenario in which a gas-rich disk experienced a merger with Gaia-Enceladus, where pre-existing stars were dynamically heated and star formation was triggered, leading to formation of the bulk of thick disk stars.
“The evidence discussed above, particularly the work of Gallart et al. (2019), supports a scenario in which a gas-rich disk experienced a merger with Gaia-Enceladus, where the stars already present were dynamically heated, and star formation was triggered (possibly in a starburst), leading to the formation of the bulk of the stars in the thick disk.”
From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Gallart et al. (2019)
The discussion on p. 3 says the Gaia-Enceladus merger heated some pre-existing disc stars and that infalling gas likely maintained or stoked star formation in the early disc. It also reports a later peak in star formation, but does not establish that the merger triggered the formation of the bulk of thick-disc stars; it says thick-disc stars formed before, during and after the merger. (LLM, conf=0.84)
Experimental — accuracy not yet measuredHelmi et al. (2018) suggest a mass ratio of ∼4:1 for the Gaia-Enceladus merger, confirmed by Gallart et al. 2019, on the basis of the estimated stellar mass of Gaia-Enceladus, the expected stellar mass-to-halo mass ratio, and the assumption that a 10^10 M_sun thick disk stellar mass is present at the time.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
