The AMBRE project: Results from the MATISSE analysis of the ESO-FEROS archived spectra

EPJ Web of Conferences, 2012
The goal of AMBRE, a joint project between ESO and the Observatoire de la Cote d’Azur, is to provide a homogeneous determination of the stellar parameters (including mean metallicity and some chemical abundances) for the archived spectra of the FEROS ...

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations

The Astrophysical Journal Supplement Series, 2023
Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

45. Stellar Classification [PDF]

Transactions of the International Astronomical Union, 1991
As an introduction to this report I would like to cite two comments from the book MK Process and Stellar Classification (ed. by R.F. Garrison, 1984). The first is from the article by W.W. Morgan The MK system and the MK process: “The MK system furnishes a satisfactory frame of reference for stars of Population I in the solar neighborhood; but when we ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Linking the morphology of young stellar objects to their evolutionary stages with self-organizing maps

Astronomy & Astrophysics
Context. Many studies in the past few decades have investigated the evolution of young stellar objects based on their spectral energy distribution. This distribution is heavily affected not only by the evolutionary stage, but also by the morphology of ...
