650 Amalasuntha
650 Amalasuntha is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on October 4, 1907, at Heidelberg. It was named after Amalasuntha, the queen of the Ostrogoths from 526 to 534 AD. The name may have been inspired by the asteroid's provisional designation ''1907 AM''. Photometric observations of this asteroid during 2007 at the Organ Mesa Observatory in Las Cruces, New Mexico, were used to create a light curve plot. This showed a rotation period of 16.582 ± 0.001 hours and a brightness variation of 0.44 ± 0.03 magnitude during each cycle.

August Kopff
August Kopff (February 5, 1882 – April 25, 1960) was a German astronomer and discoverer of several comets and asteroids. Kopff studied and worked in Heidelberg, getting his PhD there in 1906 and he then joined the Humboldt University of Berlin where he became the Director of the Institute for Astronomical Calculation. He discovered some comets, including periodic comet 22P/Kopff and the non-periodic C/1906 E1. He discovered a number of asteroids, including notably the Trojan asteroids 617 Patroclus and 624 Hektor 624 Hektor is the largest Jupiter trojan and the namesake of the Hektor family, with a highly elongated shape equivalent in volume to a sphere of approximately 225 to 250 kilometers diameter. It was discovered on 10 February 1907, by astronomer .... The lunar crater '' Kopff'' is named after him, as is the asteroid 1631 Kopff. Minor planet 805 Hormuthia is named after his wife, Hormuth.

Photometry (astronomy)
Photometry, from Greek '' photo-'' ("light") and '' -metry'' ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric photometer that converts light into an electric current by the photoelectric effect. When calibrated against standard stars (or other light sources) of known intensity and colour, photometers can measure the brightness or apparent magnitude of celestial objects. The methods used to perform photometry depend on the wavelength region under study. At its most basic, photometry is conducted by gathering light and passing it through specialized photometric optical bandpass filters, and then capturing and recording the light energy with a photosensitive instrument. Standard sets of passbands (called a photometric system) are defined to allow a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnitude (astronomy)
In astronomy, magnitude is a unitless measure of the brightness Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, ... of an astronomical object, object in a defined passband, often in the visible spectrum, visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus. The scale is Logarithmic scale, logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Thus each step of one magnitude is \sqrt[5] \approx 2.512 times brighter than the magnitude 1 higher. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values. Astronomers use two different defini ...

Rotation Period
The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the background stars, measured in sidereal time. The other type of commonly used rotation period is the object's synodic rotation period (or ''solar day''), measured in solar time, which may differ by a fraction of a rotation or more than one rotation to accommodate the portion of the object's orbital period during one day. Measuring rotation For solid objects, such as rocky planets and asteroids, the rotation period is a single value. For gaseous or fluid bodies, such as stars and gas giants, the period of rotation varies from the object's equator to its pole due to a phenomenon called differential rotation. Typically, the stated rotation period for a gas giant (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as d ...

Light Curve
In astronomy, a light curve is a graph of light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y axis and with time on the x axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic variables, and transiting extrasolar planets, or aperiodic, like the light curve of a nova, a cataclysmic variable star, a supernova or a microlensing event or binary as observed during occultation events. The study of the light curve, together with other observations, can yield considerable information about the physical process that produces it or constrain the physical theories about it. Variable stars Graphs of the apparent magnitude of a variable star over time are commonly used to visualise and analyse their behaviour. Although the categorisation of variable star types is increasingly done from their s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ostrogoths
The Ostrogoths ( la, Ostrogothi, Austrogothi) were a Roman-era Germanic peoples, Germanic people. In the 5th century, they followed the Visigoths in creating one of the two great Goths, Gothic kingdoms within the Roman Empire, based upon the large Gothic populations who had settled in the Balkans in the 4th century, having crossed the Lower Danube. While the Visigoths had formed under the leadership of Alaric I, the new Ostrogothic political entity which came to rule Italy was formed in the Balkans under the influence of the Amal dynasty, the family of Theodoric the Great. After the death of Attila and collapse of the Hunnic empire represented by the Battle of Nedao in 453, the Amal family began to form their kingdom in Pannonia. Byzantine Empire, Byzantine Zeno (emperor), Emperor Zeno played these Pannonian Goths off against the Thracian Goths, but instead the two groups united after the death of the Thracian leader Theoderic Strabo and his son Recitach. Zeno then backed Theodori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amalasuntha
Amalasuintha (495 – 30 April 534/535) was a ruler of Ostrogothic Kingdom from 526 to 535. She ruled first as regent for her son and thereafter as queen on throne. A regent is "a person who governs a kingdom in the minority, absence, or disability of the sovereign." In Amalasuintha’s case it was the minority of her son Athalaric who was only 10 at the time of her father and King Theodoric’s death. After the fall of the Western Roman Empire, the Ostrogothic Kingdom’s borders stretched a little farther than modern-day Italy’s borders. Amalasuintha was highly educated, especially as a woman in the 6th century, a time where education for any human was extremely rare. In fact, she was praised by both Cassiodorus, and Procopius for her wisdom and her ability to speak three languages, (Greek, Gothic, Latin). Along with being wise, she was known for her Roman virtues and values, which became an issue amongst her inner circle of people during her regency. Of all the things to have ...
