Sentences with phrase «type of binary system»

The worlds are aptly named «circumbinary planets» («circum» meaning around, and «binary» referring to two objects), and in this type of binary system, the two stars orbit each other while the planet orbits the two stars (pictured above).

«The fact that this supernova event didn't expel the other star, which is 20 to 25 times the mass of our sun, makes this an incredibly rare type of binary system.»

Astronomers studying two rare types of binary systems containing rapidly spinning neutron stars called pulsars have observed some unique behavior — these pulsars consume their mates.

Not exact matches

[3] Type Ia Supernovae occur when an accreting white dwarf in a binary star system slowly gains mass from its companion until it reaches a limit that triggers the nuclear fusion of carbon.

«Our knowledge of binary evolution suggests that, if the companion star can survive the transition, brown dwarfs should be common in this type of system.

Observations of the explosions of white dwarf stars in binary systems, so - called Type Ia supernovae, in the 1990s then led scientists to the conclusion that a third component, dark energy, made up 68 % of the cosmos, and is responsible for driving an acceleration in the expansion of the universe.

The main types of false positives are then EBs that are observed directly («undiluted binaries»), and EBs whose light is diluted by a nearby third star, which might be physically related to the system (triple star system) or be unrelated, with a third star being close to the line of sight to the binary system.

In consequence, this population will typically be of later spectral types, which presents lower fractions of binary systems (Lada 2006); hence the impact of false alarms from faint EBs is less for deeper samples.

In the original work by Brown, slightly different classes of false positives were used: MPU (main - sequence star with a giant planet); MSU (undiluted binaries); and the two types of diluted binaries, MSDF (an eclipsing binary + a third non-related star) and MSDT (triple systems).

In Type 1 supernovas, one star in the binary system is a white dwarf, a dying star that has consumed almost all of its hydrogen.

A Type Ia supernova results from a white dwarf that's part of a binary system (that is, one that shares an orbit with another star) and was about twice the size of our sun during its life.

Kaltenegger, L. & Haghighipour N., Calculating the Habitable Zone of Binary Star Systems I: S - type Binaries, ApJ, 777, 2, 165, 11 pp., 2013

late stages of stellar evolution: white dwarfs, isolated and in interacting binary systems, stellar explosions on white dwarfs (novae and type Ia supernovae).

Recent progress has been made to address this: (1) the discovery that gamma Cas is an eccentric binary system (P = 203.59 d) with unknown secondary type, (2) the accumulation of RXTE data at 9 epochs in 1996 - 2000, and (3) the collation of robotic telescope B, V - band photometric observations over 4 seasons.

Thus, US 708 could have originally resided in an ultra compact binary system, transferring helium to a massive white dwarf companion, ultimately triggering a thermonuclear explosion of a type Ia supernova.

Type Ia supernovae are fairly rare in the nearby Universe and represent the explosion of at least one white dwarf star in a binary system.

Previously, I focused on close binary star systems, mostly W UMa - types, and explored the evolutionary track of these types of pairs.

Observing such systems before they merge reveals crucial information about late - stage stellar evolution, binary interactions, and the types of gravitational - wave signals we expect to find with current and future observatories.

In the early 1990s, one study found that coplanarity between the orbital and equatorial planes of nearby binaries (within 100 parsecs or 326 ly) that are composed of Sol - type stars (F5 - K5 V) «exists» for binaries with orbital separations up to the average orbital distance of Pluto in the Solar System — roughly 40 times the Earth - Sun distance or «astronomical unit» (AU).

Researchers using data from Hubble's now - retired Wide Field Planetary Camera 2 (WFPC2) have identified two types of blue stragglers in Messier 30: those that form in near head - on collisions with one another and those that are in twin (or binary) systems where the less massive star siphons «life - giving» hydrogen from its more massive companion.

understand how instructions are stored and executed within a computer system; understand how data of various types (including text, sounds and pictures) can be represented and manipulated digitally, in the form of binary digits

But perhaps more revealing were her comments that the school system was no longer a «binary world», with more choice and variety in the types of school.

For a binary options system claiming to be connected to Wall Street type traders, you can expect a plethora of promises.
