They are likely created in a close binary star system consisting of a white dwarf and either a main sequence, sub-giant, or red giant star. Also with similar names are the much more energetic supernovae (SNe) and kilonovae.Ĭlassical nova eruptions are the most common type of nova. Luminous red novae share the name and are also cataclysmic variables, but are a different type of event caused by a stellar merger.
They are all considered to be cataclysmic variable stars. The main sub-classes of novae are classical novae, recurrent novae (RNe), and dwarf novae. All observed novae involve closely located binary stars (the progenitors), either a pair of red dwarfs in the process of merging, or a white dwarf and another star. Novae involve an interaction between two stars that cause the flareup that is perceived as a new entity that is much brighter than the stars involved.Ĭauses of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars. Other analyzers require up to 18 minutes to provide the same results.Wikipedia (5.00 / 1 vote) Rate this definition:Ī nova (plural novae or novas) or classical nova (CN, plural CNe, or Q) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star, that slowly fades over several weeks or many months. In settings where back to back sampling is common, Stat Profile Prime can analyze 4 samples in only 5 minutes. Stat Profile Prime eliminates the sample-to-sample delay common to older cartridge systems. Each cartridge is ready to use and easily replaced in seconds, compared to the hour or more needed for older cartridge systems. Stat Profile Prime cartridges add a significant benefit in analyzer uptime. Calibration and QC are performed automatically to maintain constant readiness. Stat Profile Prime is always ready to deliver a 9-test profile in just 60 seconds. One of the smallest and lightest cell culture analyzers, Stat Profile Prime is so compact that it can be located anywhere in the facility or operated on a mobile cart with battery back-up. Stat Profile Prime provides a supplement to liquid QC: SQM continuously monitors the status and performance of all analytical components (including sensors, reagents, calibrations, sample integrity, software, and electronics), providing real-time, sample-to-sample assurance of correct performance. Stat Profile Prime combines both automated, true liquid QC and continuous electronic self-monitoring to ensure lab accuracy and uncompromised quality. Nova’s MicroSensor cards, calibration cartridges, and QC cartridges offer a maintenance-free solution to cell culture monitoring. Onboard quality control (QC) cartridges perform QC automatically, saving time and labor. Snap-in cartridges are easy to replace and avoid prolonged calibrations common to older cartridge based systems. All sensors are contained in one MicroSensor Card.
Unique probe and flow path protects the analyzer from the flow path blockages.
