Chinthamani Ragoonatha Chary
Chinthamani Ragoonatha Chary (1822 or "17 March" 1828 – 5 February 1880) was an Indian astronomer who worked at the Madras Observatory along with N.R. Pogson. He was the first Indian Fellow of the Royal Astronomical Society and is known for his studies of variable stars and the discovery of ''R Reticuli'' in 1867. Early life Little is known about Chary's personal life. It is believed that he was born in Madras in about 1822. However, in official records, his birthdate has been recorded as 1828 and given in some sources as 17 March. Chary's ancestors were Hindu astronomers who prepared Hindu astrological almanacs called ''Panchangam''s. He lived in Nungambakkam and joined the Madras Observatory in 1840 as a "coolie" under Thomas Glanville Taylor. Career By 1864, Chary had gathered enough knowledge of mathematics to be appointed as astronomer at the observatory. He forged a productive partnership with N. R. Pogson, director of the Madras observatory. His main responsibil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century Indian Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Astronomy
Astronomy has long history in Indian subcontinent stretching from pre-historic to modern times. Some of the earliest roots of Indian astronomy can be dated to the period of Indus Valley civilisation or earlier. Astronomy later developed as a discipline of Vedanga, or one of the "auxiliary disciplines" associated with the study of the Vedas,Sarma (2008), ''Astronomy in India'' dating 1500 BCE or older. The oldest known text is the ''Vedanga Jyotisha'', dated to 1400–1200 BCE (with the extant form possibly from 700 to 600 BCE). Indian astronomy was influenced by Greek astronomy beginning in the 4th century BCEHighlights of Astronomy, Volume 11B: As presented at the XXIIIrd General Assembly of the IAU, 1997.

Drigganita
Drigganita (ದೃಗ್ಗಣಿತ; IAST: dṛggaṇita, from dṛk-gaṇita, "sight-calculation"), also called the Drik system, is a system of astronomical computations followed by several traditional astronomers, astrologers and almanac makers in India. In this system the computations are performed using certain basic constants derived from observations of astronomical phenomena. The almanacs computed using the methods of Drigganita are referred to as Drigganita Panchngas. In Tamil speaking world, they are also known as ''Thiru-ganita Panchangas''. The Drigganita system is in contrast to the method followed by some other almanac makers who use the values given in the ancient astronomical treatise known by the name Surya Siddhanta. The almanacs computed using this treatise are known as ''Sydhantic Panchangas''. They are also known as ''Vakya Panchangas''. In the history of astronomy in India, two different Drigganita systems have been introduced at two different points of time ...

William Stephen Jacob
William Stephen Jacob (1813–1862) was an English immigrant astronomer in India, who acted as the director of the Madras Observatory from 1848 to 1859. His early claim of 1855 to have detected an exoplanet, in orbit around 70 Ophiuchi, is now thought to have been mistaken. Life The seventh child of Stephen Long Jacob (1764–1851), vicar of Woolavington, Somerset, he was born at his father's vicarage on 19 November 1813; John Jacob (1812–1858) was his brother, and Sir George le Grand Jacob a cousin. He entered Addiscombe College as an East India Company cadet in 1828, passed for the engineers, and completed his military education at Royal Engineer Establishment, Chatham. After Jacob's arrival at Bombay in 1831, he spent some years with the Great trigonometrical survey in the North-West Provinces, and established a private observatory at Pune in 1842. Bad health meant he took sick leave at the Cape of Good Hope. He became assistant to Andrew Scott Waugh, but again fell i ...

Meridian Circle
The meridian circle is an instrument for timing of the passage of stars across the local meridian, an event known as a culmination, while at the same time measuring their angular distance from the nadir. These are special purpose telescopes mounted so as to allow pointing only in the meridian, the great circle through the north point of the horizon, the north celestial pole, the zenith, the south point of the horizon, the south celestial pole, and the nadir. Meridian telescopes rely on the rotation of the sky to bring objects into their field of view and are mounted on a fixed, horizontal, east–west axis. The similar transit instrument, transit circle, or transit telescope is likewise mounted on a horizontal axis, but the axis need not be fixed in the east–west direction. For instance, a surveyor's theodolite can function as a transit instrument if its telescope is capable of a full revolution about the horizontal axis. Meridian circles are often called by these names, altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
