What event most likely created the atoms of gold found in your jewelry or electronics?
What event most likely created the atoms of gold found in your jewelry or electronics? The first gravitational waves were detected in 2015 by the LIGO observatories in Washington and Louisiana.
What is a protostar quizlet?
Protostar. A contracting cloud of gas and dust with enough mass to form a star.
What is the origin of short gamma ray bursts quizlet?
What is the origin of short gamma ray bursts? It is not known but it may be the collision of a neutron star with a black hole. Observationally, how can we tell the difference between a white-dwarf supernova and a massive-star supernova?
Will our sun ever undergo a white dwarf supernova explosion Why or why not?
Explanation: Our sun is too small to go nova or supernova. It will ultimately enter a red giant stage and then collapse as a white dwarf. It would need to be at least eight times more massive to nova.
What is the most likely origin of the gold found on Earth?
All of the gold found on Earth came from the debris of dead stars. As the Earth formed, heavy elements such as iron and gold sank toward the planet's core. If no other event had occurred, there would be no gold in the Earth's crust. But, around 4 billion years ago, Earth was bombarded by asteroid impacts.
How is gold formed in stars?
Gold, like most heavy metals, are forged inside stars through a process called nuclear fusion. In the beginning, following the Big Bang, only two elements were formed: hydrogen and helium. A few hundred million years after the Big Bang, the first stars were blazing away with their nuclear fires.
What is at Tauri star quizlet?
T Tauri stars are a class of variable stars named after their prototype – T Tauri. They are found near molecular clouds and identified by their optical variability and strong chromospheric lines. T tauri wind.
How a protostar becomes a star?
If the protostar can reach a temperature of 10 million degrees kelvin, the hydrogen fusion process will start and it will become an actual star.
What is a gamma-ray bursts quizlet?
-Gamma ray bursts occur is distant galaxies but they shine so brightly in the sky that they must be the most powerful explosions we have ever seen. -Gamma ray bursts appear to come from unusually powerful supernova.
What causes the radio pulses of a pulsar quizlet?
What causes the radio pulses of a pulsar? As the neutron star spins, beams of radio radiation sweep through space. If one of the beams crosses the Earth, we observe a pulse.
What kind of star is most likely to become a white dwarf supernova?
A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth. This makes white dwarfs one of the densest forms of matter, surpassed only by neutron stars and black holes.
Will our sun become a black hole?
Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.
How do stars produce gold?
Gold, like most heavy metals, are forged inside stars through a process called nuclear fusion. In the beginning, following the Big Bang, only two elements were formed: hydrogen and helium.
Where is gold most likely to be found?
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.
What stars produce gold?
Caption: New research suggests binary neutron stars are a likely cosmic source for the gold, platinum, and other heavy metals we see today. Most elements lighter than iron are forged in the cores of stars.
What type of star produces gold?
Neutron Stars Neutron Stars Create Gold and Platinum in Their Wake.
What type of star is T Tauri?
variable stars Named for the first of their type observed, T Tauri stars are variable stars which show both periodic and random fluctuations in their brightnesses. They are newly-formed (< 10 million years old) low to intermediate mass stars (< 3 solar masses) with central temperatures too low for nuclear fusion to have started.
What is the most common type of star quizlet?
Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that they're much cooler than stars like our Sun.
What were the elements formed in red giant star?
The dying star expands into a red giant, and this now begins to manufacture carbon atoms by fusing helium atoms. More massive stars begin a further series of nuclear burning or reaction stages. The elements formed in these stages range from oxygen through to iron.
What would happen if the sun suddenly became a black hole without changing its mass quizlet?
What would happen if the Sun suddenly became a black hole without changing its mass? The black hole would quickly suck in the Earth. Earth would gradually spiral into the black hole.
What causes gamma ray bursts?
Scientists now know that the vast majority of gamma-ray bursts are "long bursts"longer than 2 seconds. They are thought to occur when a massive star runs out of fuel. Without a force to resist the crush of its own gravity, the core of the star collapses into a black hole.
Why do neutron stars emit periodic pulses of light quizlet?
These pulses are produced as beams of radio waves from a neutron star's magnetic poles sweep past the Earth. -The pulse rate of many pulsars is slowing steadily. This reflects the gradual slowing of the neutron star's rotation as it radiates energy into space.
What does a pulsar emit?
Pulsars emit cones of bright radio emission from their magnetic poles as they rotate rapidly. Because these stellar remnants can spin so quickly, their outermost magnetic field lines cannot move fast enough and do not reconnect. Pulsars are rapidly rotating, highly magnetic compact stars.
Which star is most likely to become a supernova?
The nearest stars likely to go supernova within the next few million years are Betelgeuse and Antares. Both are over 400 light years away, far more than the 30 light years at which the explosion could become dangerous. Another VERY massive star, Eta Carinae, visible in the southern hemisphere, could go even sooner.
Which star is most likely to become a white dwarf?
A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth. This makes white dwarfs one of the densest forms of matter, surpassed only by neutron stars and black holes.

What kind of star makes gold?
neutron stars Two neutron stars collide somewhere in the depths of space in this artist's concept. In addition to generating gravitational waves, such an event can produce many heavy elements, including gold.
Where do you find gold in electronics?
Gold is used in electronic devices because it is durable, has good electrical conductivity, and is less prone to corrosion. You will find traces of the precious metal on internal modems, drives, random access memory chips, motherboards, and central processing units.
Why is gold found in quartz?
Gold is formed naturally in quartz deposits in the earth. When erosion takes place, exposed veins of gold break off and wash into rivers and streams. The natural movement of the water tumbles the gold against sand and rocks, forming the Natural Gold Nugget.
