del Sco = 7 Sco = Dschubba. A spectroscopic triple and occultation |
|
|
quadruple. |
|
|
Intensity Interferometer Limb-darkened diameter 0.46 +/- 0.04 mas. |
HBr1974 |
|
1973.22, 1973.45: The new component here appears to have a much longer |
|
|
period than the 20-day single-line SB reported by van Hoof et al. |
|
|
(1963 ApJ, 137, 824). |
Lab1974 |
|
1981.4767 and other observations through 1981.4929: Companion |
HBr1974 |
|
discovered by intensity interferometry (Hanbury Brown et al. 1974). |
|
|
Delta m in the visible is about 2. |
Bag1984b |
|
1993.415: observations with MAPPIT on 3.9m AAT; maximum separation of |
|
|
apertures was 3.3m. Paper gives orbit. |
Bed1993 |
|
Miroshnichenko et al. (2001) give a combined spectroscopic/ |
Mko2001 |
|
interferometric orbit, adopting P and e from Hartkopf et al. (1996). |
Hrt1996a |
|
Combined spectroscopic/astrometric solution. Tango et al. (2009) |
Tng2009 |
|
derive masses 15 +/- 7 and 8.0 +/- 2.6 Msun, based on their mass |
|
|
function and brightness ratio, together with the ZAMS model grid of |
|
|
Tout et al. (1996 MNRAS 281, 257). The resulting dynamical parallax of |
|
|
7.03 +/- 0.15 mas agrees well with the revised Hipparcos parallax of |
|
|
6.65 +/- 0.89 (van Leeuwen 2007, ASSL vol. 350). |
|
|
Tycner et al. (2011) give a combined spectroscopic/astrometric |
NOI2011b |
|
solution, based on spectroscopicdata of Miroshnichenko et al. (2001), |
Mko2001 |
|
published astrometry, 2 measures obtained with the NPOI array in 2000, |
|
|
and 94 additional NPOI measures obtained over the years 2005-2010. The |
|
|
timing of periastron passage has been revised to UT 2011 Jul 6 +/- 2d. |
|
|
Expected minimum separation at closest approach is predicted to be |
|
|
6.14 +/- 0.07 mas (14 stellar radii). |
|
|
Malkov et al. (2012) derive dynamical and photometric masses of |
|
|
28.41 +/- 11.43 and 20.39 Msun, respectively. |
Mlk2012 |
|
Che et al. (2012) derive an orbit of del Sco based on data from NPOI |
|
|
and CHARA Array. Total mass 28 +/- 11 Msun, with the large error bar |
|
|
resulting from uncertainty in parallax estimate. Individual masses |
|
|
estimated at 13.9 (from photometry and spectroscopy) and ~6 Msun |
|
|
(based on mass ratio from RV measurements during periastron). |
CIA2012c |
|
The disk dissipates near apastron and then begins reforming as the |
XXX2020d |
|
companion approaches periastron. The V magnitude is variable over the |
|
|
orbit but it is unclear if this is due to the secondary or interaction |
|
|
between the primary and the disk. |
