Kinematic distances of Planetary Nebulae
Published online by Cambridge University Press: 18 September 2017
Extract
Most distances of planetary nebulae are known roughly within a factor of 2 or larger, except for some special objects for which the uncertainty can be as low as 50%. In the present work both IUE interstellar Lyman alpha profiles and 21 cm HI line surveys are used to infer the distances of four planetary nebulae.
