Zehnfarbenphotometrie der vier Ap‐Sterne HD 27309, HD 119213, HD 170000 und HD 192913

Astronomische Nachrichten, 1976
AbstractEs werden die Resultate einer Zehnfarbenphotometrie der vier Ap‐Sterne HD 27309, HD 119213, HD 170000 und HD 192913 mitgeteilt. Die Perioden konnten zu 2.7098, 2.433, 1.716 und 16.3 Tagen bestimmt werden. Die Amplituden‐Wellenlängen‐Beziehung zeigt für alle vier Ap‐Sterne einen unterschiedlichen Verlauf.

Planetary Companions to HD 136118, HD 50554, and HD 106252

Publications of the Astronomical Society of the Pacific, 2002
Precise Doppler observations at Lick Observatory have revealed a substellar companion orbiting the F9 V star HD 136118 with an orbital period P=1209 ± 24 days, velocity semiamplitude K = 212 ± 6 m s–1, and eccentricity of 0.37 ± 0.025. The assumed stellar mass of 1.24 yields a Keplerian companion with M sin i = 11.9 MJ and semimajor axis of 2.3 AU.

Next-generation Mapping With HD Grid and Hd Wave

Future Cardiology, 2021
High-definition (HD) mapping with the Advisor HD Grid and HD Wave Solution software offers unparalleled resolution in mapping complex arrhythmias. The unique shape of a HD Grid (16 electrodes in a 4 × 4 pattern) allows for the mapping of orthogonal electrograms (EGMs).

Phenotype Characterization of HD Intermediate Alleles in PREDICT-HD [PDF]

open access: possibleJournal of Huntington's Disease, 2016
Background: Huntington disease (HD) is a neurodegenerative disease caused by a CAG repeat expansion on chromosome 4. Pathology is associated with CAG repeat length. Prior studies examining people in the intermediate allele (IA) range found subtle differences in motor, cognitive, and behavioral domains compared to controls.
