- An A-type main-sequence star (AV) or A dwarf star is a main-sequence (hydrogen burning) star of spectral type A and luminosity class V (five). These stars have spectra defined by strong hydrogen Balmer absorption lines. They measure between 1.4 and 2.1 solar masses (M☉) and have surface temperatures between 7,600 and 10,000 K. Bright and nearby examples are Altair (A7), Sirius A (A1), and Vega (A0). A-type stars do not have convective zones and thus are not expected to harbor magnetic dynamos. As a consequence, because they do not have strong stellar winds, they lack a means to generate X-ray emissions.
- Democratic-Republican Party (Wikipedia)
The Republican Party, known retroactively as the Democratic-Republican Party (also referred to by historians as the Jeffersonian Democratic Party), was an American political party founded by Thomas Jefferson and James Madison in the early 1790s. It championed liberalism, republicanism, individual liberty, equal rights, separation of church and state, freedom of religion, decentralization, free markets, free trade, and agrarianism. In foreign policy it was hostile to Great Britain and the Netherlands and in sympathy with the French Revolution and Napoleonic wars. The party became increasingly dominant after the 1800 elections as the opposing Federalist Party collapsed.
