2010/11/1
At wide separations, planetary-mass and brown dwarf companions to solar type stars occupy a
curious region of parameters space not obviously linked to binary star formation or solar-system scale plan...
On planetary mass determination in the case of super-Earths orbiting active stars. The case of the CoRoT-7 system

Stars post-AGB – planetary nebulae general – surveys general
2010/11/1
In this review we cover the detection, identification and astrophysical importance of planetary nebulae (PN). The legacy of the historic Perek & Kohoutek and Acker et al. catalogues is briefly covered...
Wolf-Rayet Central Stars of Planetary Nebulae: Their Evolution and Properties
Solar and Stellar Astrophysics (astro-ph.SR)
