(PDF) The Horizontal Branch morphology in Globular ...

The horizontal branch (HB) is a stage of stellar evolution that immediately follows the red giant branch in stars whose masses are similar to the Sun's. Horizontal-branch stars are powered by helium fusion in the core (via the triple-alpha process) and by hydrogen fusion (via the CNO cycle) in a shell surrounding the core.The onset of core helium fusion at the tip of the red giant branch ...

Background. The size of the inoculum that initiates infection in HIV-1 is unknown, although the loss of diversity is thought to be substantial following both horizontal [1-7] and vertical [8,9] transmission.If the bottleneck is selectively neutral, genetic drift will occur because only a small number of variants are chosen at random from the population to propagate the new infection.

Pursuant to the discovery that the horizontal branches of some globular clusters exhibit very blue tails, attention is given to the instability that has been found at the end of central He-burning: here, a large increase in the size of the convective core gives rise to He-spikes sometimes called 'breathing pulses'. Semiconvection is presently adopted as a basis for this type of instability ...

Each individual fixture drain or trap arm shall connect horizontally to the wet-vented horizontal branch drain or shall be provided with a dry vent. The trap to vent distance shall be in accordance with Table 10-I. Only the fixtures within the bathroom groups shall connect to the wet-vented horizontal branch drain.

The Horizontal Branch as a probe of stellar population …

This hypothesis (originally based on the correlation between some horizontal branch morphologies - especially the existence of blue tails - and chemical spreads) provides a useful and conceptually simple key to interpret the horizontal branch peculiarities (e.g. some of its gaps) and the distribution of abundance anomalies.

CiteSeerX — Internal rotation of subdwarf B stars ...

The horizontal branch phase of a star's life is much shorter than the Main Sequence phase of its lifetime. The star will convert all of its core helium into carbon and oxygen, and then fusion will end once again. The core will again begin to collapse inward with no radiation pressure to support it.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Observations of the rotation rates of horizontal branch (HB) stars show puzzling systematics. In particular, cooler HB stars often show rapid rotation (with velocities in excess of 10 km/s), while hotter HB stars (those with Teff in excess of 11,000K) typically show much smaller rotation velocities of 8 km/s or less.

Astrophysicists produce the first age map of the halo of ...

We find that red, blue, and extreme horizontal branch stars are all produced under the effects of tidally enhanced stellar wind without any additional assumptions on the mass-loss dispersion. Furthermore, the horizontal branch morphology is found to be insensitive to the tidal enhancement parameter, Bw.

vent. Horizontal vent pipes forming branch vents, relief vents or loop vents shall be at least 6 inches (152 mm) above the flood level rim of the highest fixture served. It is important to note that the 2006 IPC has a definition of vertical pipe as any pipe which is 45°or greater from horizontal. The vent piping in this drawing is considered to

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.

However, the difference in the evolving mass may play a role in the morphology of the horizontal branch, and in particular in the formation of blue tails, in those globular clusters which show strong CNO abundance variations, such as M13 and NGC 6752. ...

Abstract. Several globular clusters with the same values of the primary parameters (age and chemical composition) show different horizontal branch (HB) morphologies, which may also be characterized by gaps or bimodal stellar distributions.
