A Jovian analogue orbiting a white dwarf star
Studies, have shown that the remnants of destroyed planets and debris-disk planetesimals
can survive the volatile evolution of their host stars into white dwarfs,, but few intact planetary …

RV-detected planets around M dwarfs: Challenges for core accretion models
Context. Planet formation is sensitive to the conditions in protoplanetary disks, for which
scaling laws as a function of stellar mass are known. Aims. We aim to test whether the …
