Symmetries and Phases in the Universe

Cosmology is a broad interdisciplinary research discipline involving different fields of physics. The main goal of the Excellence Cluster Universe is to face the fundamental challenges of modern cosmology by bridging the gap between the astrophysics and the particle/nuclear physics communities.

Massive Stars and the Gaia-ESO Survey

Despite their importance for the star-formation history of the Universe, massive stars are particularly poorly understood. However, thanks to projects such as the ongoing Gaia-ESO Survey (GES) and the VLT-Flames Tarantula Survey (VFTS) progress in the number of massive stars with accurate parameters is rapidly growing.

Revolution in Astronomy with ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) has been producing a growing number of impressive and scientifically compelling results as the most powerful mm/submm interferometer in the world. Held in central Tokyo, the aim of this four day conference is to highlight the most recent science results from ALMA obtained during the first three years of science operations, and to motivate future collaboration among researchers around the world.

The Early Life of Stellar Clusters

The goal of the workshop is to bridge the artificial divide between the fields of star formation and stellar dynamics. Star formation provides the initial conditions for the long term evolution of stellar clusters, while the dynamics of stars in clusters after star formation has ceased can inform on the conditions that have prevailed in the environment in which the clusters have formed.

RASPUTIN: Resolved And unresolved Stellar PopUlaTIoNs

The study of stellar populations is one of the most relevant diagnostics to constrain galaxy formation and evolution. Quantitative analyses of the stellar content of stellar systems pave the way to `convert’  starlight into physical quantities like stellar masses, chemical abundances and star formation rates, and to trace back in time the evolution and the chemical enrichment history of galaxies.

Physics and Evolution of Magnetic and Related Stars

The Special Astrophysical Observatory of the Russian Academy of Sciences will organize a traditional International conference “Physics and Evolution of Magnetic and Related stars” during the period from August 25 to August 31, 2014.

19° European Workshop on White Dwarfs

The 19th European Workshop on White Dwarfs will be held in Montréal, Canada on August 11-15th, 2014. This meeting will be marking the 40th anniversary of this series of workshops which started in Kiel, Germany, in 1974. The topics to be covered at the conference will be similar to those of the previous meetings.

Physics of Neutron Stars

This will be the 10th gathering on neutron star physics in Saint Petersburg (after those in 1988, 1992, 1995, 1997, 1999, 2001, 2005, 2008, and 2011). In 2014 the conference will commemorate the 100th birthday of Yakov Borisovich Zel’dovich (1914—1987), the famous Soviet physicist and astrophysicist. The conference will cover all major topics of observations and theory of neutron stars, including rotation powered pulsars, pulsar emission mechanisms, pulsar wind nebulae, magnetars, isolated cooling neutron stars, central compact objects, accreting X-ray pulsars (particularly, millisecond pulsars), neutron stars in low-mass X-ray binaries, X-ray bursts, equation of state, structure and evolution of neutron stars, mechanisms of supernova explosions and neutron star mergers.

Cool Stars, Stellar Systems and the Sun

The “Cambridge Workshop on Cool Stars, Stellar Systems, and the Sun” (also known as “Cool Stars”) has been running for 34 years since the first one was held in Cambridge, Massachusetts, in 1980. Previous Cool Stars venues include Santa Fe, NM; Boulder, CO; Seattle, WA; Tucson, AZ; Athens, GA; Florence, Italy; Tenerife, Spain; Hamburg, Germany; Pasadena, CA; St. Andrews, Scotland; and Barcelona, Spain. Lowell Observatory is proud to add Flagstaff, Arizona to this long list of distinguished cities.

Un gruppo di astronomi che si dedicano allo studio delle condizioni fisiche dell’Universo primordiale hanno ottenuto nuovi indizi sui processi di formazione delle prime strutture cosmiche, cioè stelle e galassie, andando ad analizzare la composizione chimica di alcune ‘stelle fossili’ che sono distribuite nelle regioni più esterne ed interne dell’alone galattico.
