New Windows on Massive Stars, Asteroseismology, Interferometry and Spectropolarimetry Proceedings of the International Astronomical Union IAU Symposium No. 307 IAU Symposium IAU Symposium 23-27 June 2014 Massive stars play a crucial role in the Universe: they are important drivers for the photometric and chemical evolution of galaxies; 307 Geneva, Switzerland they are sources of important elements, including those necessary for life; and, with their strong winds and supernova explosions, they feed the interstellar medium with momentum and kinetic energy, impacting on the star formation rate. Knowledge of the evolution 23-27 June 2014 307 23-27 June 2014 New Windows on of massive stars is important not only for stellar physics, but also for Geneva, Switzerland New Windows on probing the evolution of galaxies and their star formation histories Geneva, Switzerland throughout cosmic time. This volume provides an introduction to Massive Stars: these topics and to the techniques used to investigate the Massive Stars: properties of massive stars, including asteroseismology, spectropolarimetry, and interferometry. It highlights synergies Asteroseismology, between these new techniques and more classical methods, to create a synthetic view of massive stars, leading researchers Asteroseismology, Interferometry and towards new and innovative solutions to the most topical questions regarding the evolution of massive stars. Spectropolarimetry Interferometry and Proceedings of the International Astronomical Union Editor in Chief: Prof. Thierry Montmerle New Windows on This series contains the proceedings of major scientifi c meetings Massive Stars: held by the International Astronomical Union. Each volume Spectropolarimetry contains a series of articles on a topic of current interest in Asteroseismology, astronomy, giving a timely overview of research in the fi eld. With Interferometry contributions by leading scientists, these books are at a level and suitable for research astronomers and graduate students.

  • Six Β Cephei Stars As Seen with BRITE and from the Ground
    Six β Cephei stars as seen with BRITE and from the ground G. Handler1 and the BRITE Team2 1. Nicolaus Copernicus Astronomical Center, Bartycka 18, 00{716 Warszawa, Poland 2. BRITE Executive Science Team, several institutes in Canada, Austria and Poland We present an overview of BRITE-Constellation observations of β Cephei stars that have been assigned to the first author as contact PI. We discuss the objects individually, show the synergies with ground-based observations, possible prob- lems in the analysis and confront the quality of the results between the two types of observing method. In comparison to ground-based photometry, BRITE mea- surements result in lower noise levels in the periodogram. We note that due to longer integration times possible for some satellites, BRITE can now obtain much better results for fainter stars than previously. In addition, thanks to its better low-frequency stability, BRITE provides evidence that gravity mode pulsation is more common among β Cephei stars than previously thought. 1 Introduction The β Cephei stars are a group of massive pulsating stars that have variability periods between 2 − 7 hr, and masses between 9 − 17 M (Stankov & Handler, 2005). They have been shown to be accessible to asteroseismic methods many years ago, and initial results on the amount of convective core overshooting, differential rotation, etc. have been obtained (e.g., Pamyatnykh et al. 2004; Dupret et al. 2004). One of the prerequisites for success is that methods to identify the oscillation modes of these stars with their spherical degree and azimuthal order are reliable | which is the case for these stars.

Several other countries have expressed an interest in membership.

(To see how big the universe is, check Maps on Page 7). There are probably at least 100 billion galaxies known to man in the universe, and about 300 sextillion stars. The diameter of the known universe is at least 93 billion light years (1 light year = 9.46×1012 kilometers or 9.46×1015 meters) or 8.80×1026 meters. According to General Theory of Relativity, space expands faster than the speed of light. Due to this rapid expansion, it is not brief whether the size of the universe is finite or infinite. The expansion of the Universe is due to presence of dark energy, which is found to be 73% and dark matter (23%). There is only 4% matter found. However, even though the universe is huge and massive, it has a very small density of 9.9 ×10-30 gm per cubic centimeters (excluding stars, planets and any other celestial body).

  • Discovery of X-Ray Pulsations from a Massive Star
    ARTICLE Received 26 Jan 2014 | Accepted 1 May 2014 | Published 3 Jun 2014 DOI: 10.1038/ncomms5024 Discovery of X-ray pulsations from a massive star Lidia M. Oskinova1, Yael Naze´2, Helge Todt1, David P. Huenemoerder3, Richard Ignace4, Swetlana Hubrig5 & Wolf-Rainer Hamann1 X-ray emission from stars much more massive than the Sun was discovered only 35 years ago. Such stars drive fast stellar winds where shocks can develop, and it is commonly assumed that the X-rays emerge from the shock-heated plasma. Many massive stars additionally pulsate. However, hitherto it was neither theoretically predicted nor observed that these pulsations would affect their X-ray emission. All X-ray pulsars known so far are associated with degenerate objects, either neutron stars or white dwarfs. Here we report the discovery of pulsating X-rays from a non-degenerate object, the massive B-type star x1 CMa. This star is a variable of b Cep-type and has a strong magnetic field. Our observations with the X-ray Multi-Mirror (XMM-Newton) telescope reveal X-ray pulsations with the same period as the fundamental stellar oscillations. This discovery challenges our understanding of stellar winds from massive stars, their X-ray emission and their magnetism. 1 Institute of Physics and Astronomy, University of Potsdam, 14476 Potsdam, Germany. 2 FNRS, GAPHE, Department A.G.O., University of Lie`ge, 4000 Lie`ge, Belgium. 3 Massachusetts Institute of Technology, Kavli Institute for Astrophysics and Space Research, 70 Vassar Street Cambridge, Massachusetts 02139, USA. 4 Department of Physics and Astronomy, East Tennessee State University, Johnson City, Tennessee 37663, USA.

  • President's Message
    President’s Message Wow, what a month February has been! LIGO announced, on February 11th, that they had detected and measured gravity waves! What a breakthrough for physics and astrophysics. Dr. Amber Stuver, of LSU and LIGO Livingston, was the speaker at HRPO on Friday, Feb. 19th, during the public talk about this discovery. The guest speaker for the April 11th BRAS meeting will be Dr. Joseph Giaime, LSU professor of Physics and Astronomy, and the LIGO Livingston Observatory head. On December 3, 2015, the European Space Agency (ESA) launched the LISA Pathfinder mission, a space experiment to test and work out the procedures to observe lower frequency gravitational waves (lower than the waves detected by LIGO) emitted by different astronomical sources, such as the merging of super-massive black holes at the center of large galaxies. LISA Pathfinder has started its science mode, testing methods that are to be used in the L3 mission of ESA (a gravitational observatory to measure distortions in the fabric of space-time on the inconceivably tiny scale of a few millionths of a meter over a distance of a million kilometers). April 6th through April 10th is our annual Hodges Gardens Star Party. You can pre-register using the form on the BRAS website. If you have never attended this star party, make plans to attend this one. Clear Skies, and have a good March, John Nagle, BRAS President Canis Major – the Great Dog Position: RA 06 n12.5 to 07 27.5, Dec. -11.03° to -33.25° Named Stars: Sirius (Alpha CMa), “scorching”, “the Dog Star”, mag.
