We have several JWST programs to use direct imaging and infrared excess to search for or characterize white dwarf exoplanets orbiting nearby white dwarfs. Here are a few:
- A Search for Life Around Two Dead Stars
- We can directly image super-Earth-sized planets near the habitable zone of Sirius B with JWST/MIRI

Cold Exoplanets around M-dwarfs

We are also searching for cold planets around M-dwarfs with a JWST program

Such programs should be capable of detection small gas giant planets such as the proposed planet Wolf 359b:
- A Wolf 359 in sheep's clothing: Hunting for substellar companions in the fifth-closest system using combined high-contrast imaging and radial velocity analysis

Color composite image (at 7.7, 18 and 21 microns) from the JWST MIRI imager. Scale is about 1000 au top to bottom.

I am also part of the Consortium on Habitability and Atmospheres of M-dwarf Planets (CHAMPs) is an interdisciplinary research team whose goal is to address the broad science question: Can planets around small stars (primarily M-dwarfs, but also white dwarfs) support life, and if so, how do we best observe and characterize them?
