Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the event designation?GW190814
2. What is the detection instruments?Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo interferometer
3. Why is the second object in GW190814 special?The second object weighs about 2.53 times the mass of our Sun, which is right in the “mass gap” between the biggest neutron stars and the smallest black holes. That means it could be a very heavy neutron star or a tiny black hole.
4. How did scientists find out the masses of the objects?By listening to the “chirp” of the waves, scientists measured how fast the frequency changed and how strong the signal was. Those clues let them calculate how heavy each object was.

Gravitational Waves: Spacetime ripples generated by accelerating massive objects, propagating at the speed of light.
Compact Binary Merger: The collision and fusion of two dense stellar remnants, such as neutron stars or black holes.
Stellar Mass Gap: A range of masses (approx. 2.5-5 M☉) where few compact stellar remnants have been observed.
Equation of State: A relationship describing the pressure and density of matter, crucial for understanding neutron stars.
