Denise Stephens
Denise C. Nuttall Stephens is an associate professor of astronomy in the College of Physical and Mathematical Sciences in the Department of Physics and Astronomy at Brigham Young University. Education and research experience Stephens graduated from Brigham Young University in 1996 as an undergraduate student with a degree in physics. She received her Master's and Ph.D. in Astronomy from New Mexico State University. She completed her a postgraduate program at the Space Telescope Science Institute and at Johns Hopkins University. She joined the faculty of BYU in 2007. She studies the atmosphere of brown dwarfs, looks for and classifies binary systems, studies TNOs, and uses telescopes both on ground and in space to collect infrared data. In 2017, she and a team of undergraduates at BYU published their discovery of a new planet called KELT-16b, which was made as part of the KELT project. Her team also co-discovered the hottest known exoplanet KELT-9b the same year. Community in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flag Football
Flag football is a variant of American football where, instead of tackling players to the ground, the defensive team must remove a flag or flag belt from the ball carrier ("deflagging") to end a Down (gridiron football), down. The sport has a strong amateur following and several national and international competitions each year sponsored by various associations. In flag football, contact is limited between players. The international governing body for the sport is the International Federation of American Football (IFAF). In 2022, flag football was shortlisted as a proposed discretionary event for the 2028 Summer Olympics in Los Angeles. History The creation of the game of Flag Football can be attributed to Porter Wilson, who was the man who invented flag-a-tag belts & flags used as equipment to play the sport. The best available records to date point to the early 1940s during World War II as the sport's starting point. The game began as a recreational sport created for Americ ...

KELT-9b
KELT-9b is an exoplanet—more specifically, an ultra-hot Jupiter—that orbits the late B-type/early A-type star KELT-9, located about 670 light-years from Earth. Detected using the Kilodegree Extremely Little Telescope, the discovery of KELT-9b was announced in 2016. , it is the hottest known exoplanet. Host star The star is 2-3 times bigger and 2–5 times more massive than the sun. The surface temperature of the host star, KELT-9, is 10,170 K, unusually hot for a star with a transiting planet. Prior to the discovery of KELT-9b, only six A-type stars were known to have planets, of which the warmest, WASP-33, is significantly cooler at 7,430 K; no B-type stars were previously known to host planets. KELT-9, classified as B9.5-A0 could be the first B-type star known to have a planet. KELT-9b occupies a circular but strongly inclined orbit a mere 0.03462 AU from KELT-9 with an orbital period of less than 1.5 days.

Kilodegree Extremely Little Telescope
The Kilodegree Extremely Little Telescope (or KELT) is an astronomical observation system formed by two robotic telescopes that are conducting a survey for transiting exoplanets around bright stars. The project is jointly administered by members of Ohio State University Department of Astronomy, the Vanderbilt University Department of Physics and Astronomy Astronomy Group, the Lehigh University Department of Physics, and the South African Astronomical Observatory (SAAO). KELT Telescopes KELT consists of two telescopes, KELT-North in Arizona in the United States, and KELT-South at the SAAO observing station near Sutherland, South Africa. Each KELT telescope consists of a wide field (26 degrees by 26 degrees) medium format telephoto lens with a 4.2 cm aperture, mounted in front of a 4k x 4k Apogee CCD. Each can also be equipped with an alternative narrower field (10.8 degrees by 10.8 degrees) lens with a 7.1 cm aperture for a narrow angle campaign mode. KELT-North u ...

Trans-Neptunian Object
A trans-Neptunian object (TNO), also written transneptunian object, is any minor planet in the Solar System that orbits the Sun at a greater average distance than Neptune, which has a semi-major axis of 30.1 astronomical units (au). Typically, TNOs are further divided into the classical and resonant objects of the Kuiper belt, the scattered disc and detached objects with the sednoids being the most distant ones. As of October 2020, the catalog of minor planets contains 678 numbered and more than 2,000 unnumbered TNOs. The first trans-Neptunian object to be discovered was Pluto in 1930. It took until 1992 to discover a second trans-Neptunian object orbiting the Sun directly, 15760 Albion. The most massive TNO known is Eris, followed by Pluto, , , and . More than 80 satellites have been discovered in orbit of trans-Neptunian objects. TNOs vary in color and are either grey-blue (BB) or very red (RR). They are thought to be composed of mixtures of rock, amorphous carbon and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
