Dynamical evolution and spin-orbit resonances of potentially habitable exoplanets. The case of GJ 581d
Valeri V. Makarov, Ciprian Berghea, Michael Efroimsky
GJ 581d is a potentially habitable super-Earth in the multiple system of exoplanets orbiting a nearby M dwarf. We investigate this planet's long-term dynamics, with an emphasis on…
Correlated and zonal errors of global astrometric missions: a spherical harmonic solution
V. V. Makarov, B. N. Dorland, R. A. Gaume +4
We propose a computer-efficient and accurate method of estimation of spatially correlated errors in astrometric positions, parallaxes and proper motions obtained by space and groun…
Spitzer Observations of MF 16 Nebula and the associated Ultraluminous X-ray Source
Ciprian T. Berghea, Rachel P. Dudik
We present Spitzer Infrared Spectrograph (IRS) observations of the ultra-luminous X-ray source (ULX) NGC 6946 X-1 and its associated nebula MF 16. This ULX has very similar propert…
Quasometry, Its Use and Purpose
Valeri Makarov, Ciprian Berghea, David Boboltz +8
Quasometry is precision measurement of celestial positions and apparent motion of very distant extragalactic objects, such as quasars, galactic nuclei, and QSOs. We use this term t…
