Read and understand · 1/3What does the FLIP method model?

Read the answer and explanation

How starlight travels through a telescope. The second paragraph explains that FLIP models how starlight travels through a telescope.

Clue: The team developed a method called FLIP, which models how starlight travels through a telescope. Subtracting that model from an observation revealed the known giant planet 51 Eridani b at an infrared wavelength where an earlier analysis had missed it. The planet itself was discovered previously; this was not the discovery of a new world.

Read and understand · 2/3What does the observation show about 51 Eridani b?

Read the answer and explanation

It was a known planet recovered at a wavelength where an earlier analysis missed it.. The paragraph identifies it as a previously discovered planet that the earlier analysis missed at an infrared wavelength.

Clue: The team developed a method called FLIP, which models how starlight travels through a telescope. Subtracting that model from an observation revealed the known giant planet 51 Eridani b at an infrared wavelength where an earlier analysis had missed it. The planet itself was discovered previously; this was not the discovery of a new world.

Read and understand · 3/3What work do the authors say remains?

Read the answer and explanation

Reducing computing costs and testing larger datasets. The final paragraph identifies computing costs and larger datasets as future work.

Clue: In other tests the method was between two and 15 times more sensitive than standard glare-removal techniques. The authors say it may help researchers detect fainter planets, but reducing its computing costs and testing larger datasets remain future work.

Your turn

Explain how FLIP helped reveal 51 Eridani b and identify two tasks that remain before wider use.

See one possible answer

FLIP models the star’s light so it can be subtracted from the observation, revealing the known planet. The authors say computing costs must be reduced and larger datasets tested.
