, 2015
We show how the range of application of the principal component analysis-based inversion method of Paletou et al. (2015) can be extended to late-type stars data.

Speckle Observations With PISCO in Calern (France): II. Astrometric Measurements of Visual Double Stars in 2017–2018 and New or Revised Orbits for A1913 AB, A1710, COU1394, BU1185, A122, A570, HU577, COU812, HU332, A2095 AB, and A884

Astronomische Nachrichten, Volume 346, Issue 6, July 2025.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2017–2018 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.

Consilience in practice: social–ecological dynamics of the Lake Volvi region (Greece) during the last two millennia

Journal of Quaternary Science, Volume 40, Issue 3, Page 459-480, April 2025.
ABSTRACT The Lake Volvi area, part of the region of Macedonia (northern Greece), is a biodiversity hotspot, located in the central part of a major communication corridor connecting the western and eastern parts of the Balkans. The sediment succession from Lake Volvi is investigated here to provide a unique high‐resolution pollen and geochemical record ...

L'astragalismo antico e i parallelismi in Grecia moderna: il gioco del Vezyris e altri riti ludici

Mantichora, 2020
I devote my attention to Greek ancient plays by astragals, the knuckle-bones of animals used for games, and their parallels in Modern Greek folk-lore. These ludic rituals are known since Homeric epics and they were very well spread during Antiquity and ...

Revisiting Variable Stars Near Globular Clusters South of −29° Declination

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT We review an often‐cited but seldom‐accessed catalogue by Fourcade and Laborde (1966) of 785 variable stars near 47 southern Galactic globular clusters, and recover the locations of 85 stars that were not incorporated into subsequent variable star catalogues and hence have become “lost” to the literature.
