Helmut Arthur Abt (born 26 May 1925) [2] is a German-born American astrophysicist, having worked at the National Optical Astronomy Observatory and an Elected Fellow of the American Association for the Advancement of Science. [3] [4] [5] [6] He is astronomer emeritus at Kitt Peak National Observatory. [7] [8]

Contents

Helmut was born in Helmstedt, Germany, then his family emigrated to the United States when he was two. [2] [8] He received his B.S. in Mathematics from Northwestern University in 1946, M.S. in Physics from Northwestern University in 1948, [9] and became the first person to be awarded a Ph.D. in astrophysics at California Institute of Technology in 1952 for his thesis work on W Virginis. [6] [1]

He then spent a year at Lick Observatory. [2] From 1953 to 1959 he was assistant professor at Yerkes Observatory, part of the University of Chicago, then joined the staff of the Kitt Peak National Observatory as an astronomer, where he remained until 2000. [10] [8] From 1966 to 1968, he was President of the Astronomical Society of the Pacific. [2] During 1971–1999 he was managing editor of the Astrophysical Journal . [6]

His areas of research include stellar rotation; binary stars, including spectroscopic binaries; stellar classification; and bibliometrics of astronomy publications. [7] [8]

Awards and honors

He was awarded the George Van Biesbroeck Prize in 1997. [10] The main-belt asteroid 9423 Abt, discovered by Spacewatch at Kitt Peak National Observatory in 1996, [5] and Abt's star (SV Crateris/ HD 98088/ ADS 8115) in the constellation Crater [11] were named in his honor.

The Kitt Peak National Observatory (KPNO) is a United States astronomical observatory located on Kitt Peak of the Quinlan Mountains in the Arizona-Sonoran Desert on the Tohono Oʼodham Nation, 88 kilometers (55 mi) west-southwest of Tucson, Arizona. With more than twenty optical and two radio telescopes, it is one of the largest gatherings of astronomical instruments in the Earth's northern hemisphere.

<span class="mw-page-title-main">Star</span> Large self-illuminated object in space

A star is a luminous spheroid of plasma held together by self-gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated 1022 to 1024 stars. Only about 4,000 of these stars are visible to the naked eye—all within the Milky Way galaxy.

<span class="mw-page-title-main">70 Virginis</span> Star in the constellation Virgo

70 Virginis is a binary star located 59 light years from the Sun in the equatorial constellation of Virgo, near the northern constellation border with Coma Berenices. 70 Virginis is its Flamsteed designation. The star is visible to the naked eye as a faint, yellow-hued point of light with an apparent visual magnitude of +4.97. It is drifting further away with a heliocentric radial velocity of +4.4 km/s and has a high proper motion, traversing the celestial sphere at the rate of 0.621 arc seconds per annum.

The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on the summit of Mt. Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Mt. Cerro Pachón about 10 kilometres (6.2 mi) to the southeast. It is approximately 80 kilometres (50 mi) east of La Serena, where support facilities are located. The principal telescopes at CTIO are the 4 m Víctor M. Blanco Telescope, named after Puerto Rican astronomer Víctor Manuel Blanco, and the 4.1 m Southern Astrophysical Research Telescope, which is situated on Cerro Pachón. Other telescopes on Cerro Tololo include the 1.5 m, 1.3 m, 1.0 m, and 0.9 m telescopes operated by the SMARTS consortium. CTIO also hosts other research projects, such as PROMPT, WHAM, and LCOGTN, providing a platform for access to the southern hemisphere for U.S. and worldwide scientific research.

<span class="mw-page-title-main">Tau Tauri</span> Star system in the constellation Taurus

Tau Tauri, Latinized from τ Tauri, is a quadruple star system in the constellation Taurus. It is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.33. The distance to this system is approximately about 400 light years based on parallax. The system is moving further from the Earth with a heliocentric radial velocity of +14.6 km/s, and it is a member of the Taurion OB association, located between Orion and Taurus. It is located 0.7 degree north of the ecliptic, and thus is subject to lunar occultations.

Zeta Boötis, Latinized from ζ Boötis, is a binary star system in the constellation of Boötes. They have the Flamsteed designation 30 Boötis; Zeta Boötis is the Bayer designation. This system is visible to the naked eye with a combined apparent magnitude of +3.78. The individual magnitudes differ slightly, with component A having a magnitude of 4.46 and component B at the slightly dimmer magnitude 4.55. It is located at a distance of approximately 180 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −9 km/s.

9423 Abt, provisional designation 1996 AT7, is a stony background asteroid from the central region of the asteroid belt, approximately 13 kilometers in diameter.
