Palomar

• The star, named ZTF SLRN-2020, is located in the Milky Way galaxy, in the constellation Aquila.
• Although we only see the effects on the star, not the planet directly, our team is confident that the event we witnessed was a star swallowing its planet.

Finding a flash in the dynamic night sky

• To do this, we have been using data from the Zwicky Transient Facility, a telescope located on Palomar Mountain in Southern California.
• It takes nightly images of broad swaths of the sky, and astronomers can then compare these images to find stars that change in brightness over time, or what are called astronomical transients.
• Finding stars that change in brightness isn’t the challenge – it’s sorting out the cause behind any specific change to a star.

When a star swallows its planets

The idea that stars could engulf some of their planets has been a long-standing assumption in astronomy. Astronomers have long known that when stars run out of hydrogen in their cores, they get brighter and begin to increase in size. Many planets have orbits that are smaller than the eventual size of their parent stars. So, when a star runs out of fuel and starts to expand, the planets nearby are inevitably consumed.

Interpreting a stellar flash

• This is where combining theoretical models with the observational data allowed us to understand what the telescopes captured.
• The merging of two stars into a single, bigger star is a dramatic event that throws matter out into the stars’ surroundings.
• A large part of my career has focused on modeling the way stellar gas moves and crashes into itself and is expelled in these moments of intense interaction.
• My past research suggests that smaller planets – or ones in more-distant orbits that only get consumed once a star has grown massively in size – might be swallowed without a detectable flash.

Learning from the real thing

• First, the planet skims across the surface of the star for many years, slowly heating up and expelling material from the star’s atmosphere.
• This cloud of dust gives the star a progressively redder color and emits increasing amounts of infrared radiation.
• Next week our team will start analyzing data from the James Webb Space Telescope in the hopes of learning about the chemistry of the gas that now surrounds ZTF SLRN-2020.
