copy

A good summary should consist of these guidelines:

• Read the whole article through without stopping to get an overall feel for what is covered.
• Re-read the article again if you feel you did not 'get it'.
• Read the first and last sentences of every paragraph again. This usually works because writers start a new paragraph when introducing a new point or piece of information. They often end a paragraph with a summary of what that paragraph had in it.
• Cut out the 'filler'. There is no need to include the personal touches the author has added to make the article more enjoyable to read. Just stick to the science.
• Now start by writing one sentence for each paragraph in the article. Try to focus on the key scientific points the author is trying to get across in that paragraph.
• Read what you have written and add anything important you have omitted; cut out any repetitions or superfluous text. Edit, edit, edit.
• Read what you have written again. Try to make it read well; do not give me a list of bullet points! Write in complete grammatical sentences.
• Resources and references

What extra could be added to this?

• Neutron stars form from the dense cores left behind after supernova explosions, where internal pressure fuses subatomic particles into neutrons. The composition of these cores remains mysterious, with theories suggesting either neutron domination or more exotic states of matter. Instruments like the Neutron Star Interior Composition Explorer (NICER) on the International Space Station are crucial for precise studies of neutron stars' properties. Recent NICER measurements have provided detailed insights into neutron star mass, radius, and magnetic fields. These observations, combined with data from gravitational-wave observatories, represent a significant step forward in understanding neutron-star physics.
