This publication is the first monographic result of the APART project "Migration Phenomena in the Early La Tène Period" and the Austrian Science Fund project "The Celtic cemetery in Mannersdorf (Lower Austria) in the context of east-west cultural contact". From 1976 to 1984, Heribert Schutzbier and Friedrich Opferkuh from the Mannersdorf Museum, together with the Austrian Federal Department of Sites and Monuments, excavated a total of 96 inhumation and cremation burials from the Early and Middle La Tène periods in the field Reinthal Süd. The artefacts are of high quality, seen primarily in the use of materials such as silver, gold, glass and corals, as well as in their technical workmanship. A major find at the cemetery is a bronze situla, which was imported from northern Italy. Certain areas, like the Middle Rhine, the Champagne or the Balkan, must have been well connected to this Lower Austrian region. An analysis revealed a group of "Lt B1 elite or leading graves", with persons wearing double foot and hand bands and the graves containing precious metals. In the central Danube region, the size of the necropolis in Mannersdorf am Leithagebirge, with its 96 graves, lies midfield. According to a considered but cautious opinion, it is possible that some of those buried in Mannersdorf were a group of people originating from the area of today's Switzerland. An equally possible hypothesis is, and this does not contradict the first view, that here members of an "upper class" are represented. Printed with the support of the Austrian Science Fund (FWF). - Die hier vorliegende Publikation ist das erste Ergebnis in Monographieform des APART-Projekts "Migrationsphänomene in der Frühlatènezeit" und des FWF-Projekts P-15977-G02 "The celtic cemetery of Mannersdorf (Lower Austria) in the context of east and west cultural contact". In Mannersdorf am Leithagebirge, Flur Reinthal Süd wurden von 1976 bis 1984 vom Museum Mannersdorf durch H. Schutzbier und F. Opferkuh und dem Bundesdenkmalamt (G. Melzer) insgesamt 96 Körper und Brandgräber der Früh- und Mittellatènezeit ausgegraben. Das Gräberfeld selbst erstreckt sich in nw-so Richtung mit einer Länge von 200 und einer Breite von ca. 45 Metern. Es hat eine Belegungsdauer von Latène A2/B1 bis C1, was einer absoluten Datierung von ca. 400 bis 200 vuZ. entspricht. Die Qualität der Beigaben zeigt sich neben den Materialien Silber, Gold, Glas und Korallen vor allem in der technischen Ausführung der Artefakte. Ein markantes Stück des Gräberfeldes ist eine Bronzesitula, die ein Importstück aus Norditalien darstellt. Bestimmte Gebiete wie das Mittelrheingebiet, die Champagne und das Balkangebiet müssen damals intensive Verbindungen in den niederösterreichischen Raum gehabt haben. Zur Geschlechterverteilung im Gräberfeld ist zu bemerken, dass mit 48 Personen doppelt so viele Frauen wie Männer (24) vorkommen. Es lässt sich eine Gruppe der sogenannten "Lt B1-Elite- bzw. Spitzengräber" herausarbeiten, die sich als die höchste Ausstattungsgruppe mit Doppelfuß- und Handreifen sowie dem Vorkommen von Edelmetall definieren. Die Nekropole gehört mit ihren 96 Gräbern zu den mittelgroßen des mittleren Donaugebiets. Es zeigt sich, dass es sich bei einem Teil der in Mannersdorf Bestatteten eventuell um eine Gruppe von Menschen handelt, die aus dem Gebiet der heutigen Schweiz stammten. Eine ebenso wahrscheinliche These wäre, dass es sich um Angehörige einer "Oberschicht" handelt, die weitreichende wirtschaftliche und verwandtschaftliche Kontakte (und dadurch auch Mobilität) durch den "mitteleuropäischen Korridor" und die anschließenden Gebiete wie Norditalien hatten und dies durch ihre Tracht und den zusätzlichen Besitz zum Ausdruck brachten. Ergänzende Analysen von Bronzematerial, Keramik, Tierknochen, Eisenschmiedetechnik, Goldschmiedetechnik, Textil- und Herstellungstechnik und Steinartefakten stellen einen unverzichtbaren Teil der Darstellung dieses latènezeitlichen Gräberfeldes dar.

The extensive stellar spectroscopic datasets that are available for studies in Galactic Archeaology thanks to, for example, the Gaia-ESO Survey, now benefit from having a significant number of targets that overlap with asteroseismology projects such as Kepler, K2, and CoRoT. Combining the measurements from spectroscopy and asteroseismology allows us to attain greater accuracy with regard to the stellar parameters needed to characterise the stellar populations of the Milky Way. Aims. The aim of this Gaia-ESO Survey special project is to produce a catalogue of self-consistent stellar parameters by combining measurements from high-resolution spectroscopy and precision asteroseismology. Methods. We carried out an iterative analysis of 90 K2@Gaia-ESO red giants. The spectroscopic values of Teff were used as input in the seismic analysis to obtain log g values. The seismic estimates of log were then used to re-determine the spectroscopic values of Teff and [Fe/H]. Only one iteration was required to obtain parameters that are in good agreement for both methods and, thus, to obtain the final stellar parameters. A detailed analysis of outliers was carried out to ensure a robust determination of the parameters. The results were then combined with Gaia DR2 data to compare the seismic log with a parallax-based log and to investigate instances of variations in the velocity and possible binaries within the dataset. Results. This analysis produced a high-quality catalogue of stellar parameters for 90 red giant stars from K2@Gaia-ESO that were determined through iterations between spectroscopy and asteroseismology. We compared the seismic gravities with those based on Gaia parallaxes to find an offset which is similar to other studies that have used asteroseismology. Our catalogue also includes spectroscopic chemical abundances and radial velocities, as well as indicators for possible binary detections. © ESO 2020. ; The authors thank the International Space Science Institute in Bern (ISSI) and Beijing (ISSI-BJ) for supporting and hosting the meetings of the International Team on "AsteroStep" and "Libraries of 2020", respectively, during which the discussions leading and contributing to this publication were initiated and held.
