Abstract The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest energy photons. These were some of the extremes of Astrophysics 2006. We attempt also to bring you updates on things of which there is currently only one (habitable planets, the Sun, and the Universe) and others of which there are always many, like meteors and molecules, black holes and binaries.  
One of Everything: The Breakthrough Listen Exotica Catalog
We present Breakthrough Listen’s Exotica Catalog as the centerpiece of our efforts to expand the diversity of targets surveyed in the Search for Extraterrestrial Intelligence (SETI). As motivation,
The New Little Ice Age Has Started
The STEREO Mission: An Introduction
Abstract The twin STEREO spacecraft were launched on October 26, 2006, at 00:52 UT from Kennedy Space Center aboard a Delta 7925 launch vehicle. After a series of highly eccentric Earth orbits with
Twenty-five years of helioseismology research in Uzbekistan
The Ulugh Beg Astronomical Institute was involved in the IRIS helioseismology project from the mid-1980s through to the end of the project in 2001. This project aimed to study the deep interior of
FK Comae Berenices, King of Spin: The COCOA-PUFS Project
COCOA-PUFS is an energy-diverse, time-domain study of the ultra-fast spinning, heavily spotted, yellow giant FK Com (HD117555; G4 III). This single star is thought to be a recent binary merger, and
Grand Minimum of the Total Solar Irradiance Leads to the Little Ice Age
Quasibicentennial variation of the energy solar radiation absorbed by the Earth remains uncompensated by the energy emission to space over the interval of time that is determined by the thermal
Solar Storm Threat Analysis
But as the intensity of a solar storm increases like a wild beast, the storm can begin to develop the capacity to create a major disaster on Earth. The difference in solar storm intensity is like the
Usage bibliometrics
The state-of-the-art in usage-based informetric, i.e. the use of usage data to study the scholarly process, is reviewed.


Cosmology: Where all the lithium went
Korn et al. resolve the discrepancy in the observed amount of lithium in the oldest stars by showing that trends in the abundances of other elements are explained by diffusion turbulent mixing, which takes the lithium deep into the stars.
Cosmology: The infrared dawn of starlight
The modest-sized but successful Spitzer Space Telescope has detected fluctuations in cosmic light at infrared frequencies. Is this the signature of the first population of stars that formed in the
Probing the Faintest Stars in a Globular Star Cluster
An ultradeep color-magnitude diagram for NGC 6397 is constructed, showing a clear truncation in each of its two major stellar sequences and a turn toward bluer colors in the least luminous of these objects.
Stellar and extragalactic radiation at the Earth’s surface
Reviving a calculation made by Eddington in the 1920s, and using the most recent and comprehensive databases available on stars and galaxies, including more than 2,500,000 stars and around 20,000
On the first generation of stars
We argue that the first stars may have spanned the conventional mass range rather than be identified with the very massive objects (∼100-10 3 M ⊙ ) favoured by numerical simulations. Specifically, we
Evolution of massive AGB stars
The evolution of stars in the mass range 7-12 M⊙ is characterized by the off-center ignition of carbon in condition of partially degeneracy followed by the propagation of a convectively bound flame
Astrophysical consequences of extended cosmology
We outline astrophysical implications of a cosmological model based on the popular view that gravity should be extended from four to more dimensions to unify the forces of physics. At early times the
Young Close-By Neutron Stars: The Gould Belt Vs. The Galactic Disc
We present new population synthesis calculations of close young neutron stars. In comparison with our previous investigation we use a different neutron star mass spectrum and different initial
Astronomy: Champagne supernova
It is shown that the high-redshift supernova SNLS-03D3bb does not play by these rules: its exceptionally high luminosity and low kinetic energy imply a super-Chandrasekhar mass progenitor, so future cosmological studies may need to consider possible contamination from such events when calculating distances.
Molecular gas in the Andromeda galaxy
M 31, the closest large spiral galaxy to our own, is the best object for studying molecular clouds and their relation to the spiral structure. As one of the astronomical objects with the best known
