Astronomy & Geophysics

Astronomy & Geophysics is a peer-reviewed scientific journal published on behalf of the Royal Astronomical Society by Oxford University Press. It was established in 1997 as a replacement for The Quarterly Journal of the Royal Astronomical Society. As of 2012, it is edited by Sue Bowler (University of Leeds).

Scope

The journal covers astronomy, astrophysics, cosmology, planetary science, solar-terrestrial physics, global and regional geophysics, and the history of these subjects. It also publishes thematic articles regarding interdisciplinary research, science policy, news, opinions, correspondence, and book and software reviews. Royal Astronomical Society communications about events and people and obituaries are also within this journal's purview.

Furthermore, in keeping with the tradition of the Quarterly Journal of the Royal Astronomical Society, it publishes discussions of fundamental science and scientific debates. The journal also functions as a channel of communication between the membership, the Council, and the Society's Officers.

A2G

A2G is a studio EP by American hip hop duo Blackalicious, released in 1999 by Quannum Projects.

The EP contains the tongue-twisting song "Alphabet Aerobics".

Nova

A nova (plural novae or novas) is a cataclysmic nuclear explosion on a white dwarf, which causes a sudden brightening of the star. Novae are not to be confused with other brightening phenomena such as supernovae or luminous red novae. Novae are thought to occur on the surface of a white dwarf in a binary system when they are sufficiently near to one another, allowing material (mostly hydrogen) to be pulled from the companion star's surface onto the white dwarf. The nova is the result of the rapid fusion of the accreted hydrogen on the surface of the star, commencing a runaway fusion reaction.

Development

The development begins with two main sequence stars in a binary relation. One of the two evolves into a red giant leaving its remnant white dwarf core in orbit with the remaining star. The second star—which may be either a main sequence star, or an aging giant one as well—begins to shed its envelope onto its white dwarf companion when it overflows its Roche lobe. As a result, the white dwarf will steadily accrete matter from the companion's outer atmosphere; the white dwarf consists of degenerate matter, so the accreted hydrogen does not inflate as its temperature increases. Rapid, uncontrolled fusion occurs when the temperature of this accreted layer reaches ~20 million kelvin, initiating a burn via the CNO cycle.

Nova (eikaiwa)

Nova (formerly Nova Group) is a large eikaiwa school (private English teaching company) in Japan. It was by far the largest company of this type until its widely publicized collapse in October 2007. Before its bankruptcy, Nova employed approximately 15,000 people across a group of companies that supported the operations of and extended out from the "Intercultural Network" of its language schools. The scope of its business operations reached its peak in February 2007 following a rapid expansion of its chain to 924 Nova branches plus a Multimedia Center located in Osaka.

Nova, known for high-priced lesson packages, and later plagued by lawsuits and negative publicity, began to decline in earnest almost immediately after the Ministry of Economy, Trade and Industry placed a six-month ban against soliciting new long-term contracts from students on the company on 13 June 2007. The impending financial crisis facing Nova related to a rapid increase in refund claims, significant drops in sales figures, and deterioration of its reputation, came to the fore in September 2007 when Nova began to delay payment of wages and bonuses to staff. The NAMBU Foreign Workers Caucus in Tokyo estimated that up to 3,000 staff had not received their salaries on time. A solution for Nova's failure to pay wages was promised by 19 October in a fax sent to branch schools. On 23 October the Osaka Labor Standards office accepted a demand by unionized Nova instructors to investigate criminal charges against Nova President and founder, Nozomu Sahashi, over delayed and unpaid wages, but Sahashi was ultimately not charged.

Malta (band)

Malta was a Swedish band. It was a duo consisting of Claes af Geijerstam and Göran Fristorp. In 1973, they had to change their band name to Nova in order to perform at the Eurovision Song Contest 1973 to perform the song "You're Summer" in Luxembourg, which would put them in 5th place.
