The On/Off Nature of Star-Planet Interactions
Evgenya Shkolnik, David A. Bohlender, Gordon A. H. Walker +1
Evidence suggesting an observable magnetic interaction between a star and its hot Jupiter appears as a cyclic variation of stellar activity synchronized to the planet's orbit. In t…
Search for vertical stratification of metals in atmospheres of blue horizontal-branch stars
V. R. Khalack, F. LeBlanc, B. B. Behr +2
The observed abundance peculiarities of many chemical species relative to the expected cluster metallicity in blue horizontal-branch (BHB) stars presumably appear as a result of at…
Variations of the high-level Balmer line spectrum of the helium-strong star Sigma Orionis E
Myron A. Smith, David A Bohlender
Using the high-level Balmer lines and continuum, we trace the density structure of two magnetospheric disk segments of the prototypical Bp star sigma Ori E (B2p) as these segments…
Variations of the ultraviolet resonance lines of the Be IV-V star zeta Cassiopeiae
Myron A. Smith, David A. Bohlender
Recently Neiner et al. reported that the B2 IV-V star zeta Cas contains a weak magnetic field which varies on the same 5.37 day period found from the modulations of its N V, C IV,…
Vertical abundance stratification in the blue horizontal branch star HD135485
V. R. Khalack, F. LeBlanc, D. Bohlender +2
It is commonly believed that the observed overabundances of many chemical species relative to the expected cluster metallicity in blue horizontal branch (BHB) stars appear as a res…
