41 Sextantis (HD 93903; HR 4237; 74 G. Sextantis), or simply 41 Sex is a spectroscopic binary located in the equatorial constellation Sextans. It has an apparent magnitude of 5.79,[2] making it faintly visible to the naked eye under ideal conditions. The system is located relatively close at a distance of 310 light-years based on Gaia DR3 parallax measurements[1] and it is drifting closer with a heliocentric radial velocity of approximately −4.9 km/s.[6] At its current distance, 41 Sex's brightness is diminished by an interstellar extinction of 0.16 magnitudes[17] and it has an absolute magnitude of +0.91.[7]
The visible component has a stellar classification of kA3hA7VmA9,[3] indicating that it is an Am star with the calcium K-lines of an A3 star, the hydrogen lines and effective temperature of an A7 main-sequence star, and the metal lines of an A9 star. It has 2.23 times the mass of the Sun[9] and a slightly enlarged radius 3.10 times that of the Sun.[10] It radiates 32.6 times the luminosity of the Sun[11] from its photosphere at an effective temperature of 7,759 K,[13] giving it a white-hue when viewed in the night sky. 41 Sextantis Aa is metal-deficient with an iron abundance 58.9% that of the Sun[14] and it spins modestly with a projected rotational velocity of 24 km/s.[5]
The companion's spectrum is very weak compared to the primary, but it is said to be either a late F-type star or an early G-type star.[5] It has 105% the mass of the Sun[9] and 1.3 times the radius of the Sun.[5] It radiates 1.8 times the luminosity of the Sun from its photosphere.[5] It spins slowly with a projected rotational velocity of 10 km/s.[5]

HD 11928 (HR 564; NSV 15408) is a solitary star located in the northern constellation Triangulum. It is faintly visible to the naked eye as a red-hued point of light with an apparent magnitude of 5.85.[13] Gaia DR3 parallax measurements imply a distance of 530 light-years and it is drifting closer with a heliocentric radial velocity of −1.93 km/s.[6] At its current distance, HD 11928's brightness is diminished by an interstellar extinction of 0.13 magnitudes[14] and it has an absolute magnitude of +0.11.[7]
HD 11928 has a stellar classification of M2 III,[4] indicating that is an evolved M-type giant star. It is currently an asymptotic giant branch star that is generating energy via the fusion of hydrogen and helium shells around an inert carbon core. At present it has expanded to 52.68 times the radius of the Sun[8] and it radiates 485 times the luminosity of the Sun[9] from its photosphere at an effective temperature of 3,656 K.[11]

Motonic Route 13 (MOT-13) is a state highway located in Motonic. It runs 12.65 miles (20.36 km) from Master's Road in Mboa to Master's Road in Mom's Town. MOT-13 acts as the main road for downtown Mom's Town and it parallels Master's Road for most of its length.
Route Description
MOT-13 begins at an intersection with Master's Road in western Mboa. It heads through downtown as Louis Avenue, a four-lane undivded road with a center turn lane. It passes through several residental and business areas before meeting its final intersection within the town. Afterwards, MOT-13 exits Mboa and reduces to two lanes. It passes through the forest and several rural areas. MOT-13 then expands to a four lane divided highway and enters Mom's Town where it meets the northern terminus of MOT-204 (Comforta Road). MOT-13 continues through the northern part of the city, passing several shopping centers. After its interesection with Wayne Street/Sterling Street, MOT-13 veers northwest towards its partial cloverleaf interchange with MOT-26 (Aloys Pike). At this point, MOT-13 acts as a connector to traffic from Sterling St to eastbound MOT-26. MOT-13 veers north shortly after the interchange and ends right at Master's Road. It continues north as county-maintained Louis Avenue.
History
MOT-13 is one of the newer additions to the Motonic Highway System. As of its establishment, the route has not changed that much.
Junctions
The entire route is in Master's County.
