CEA 6 Leg 4

We being leg 4 of Celebration of Early Astronomy 6, which is the last single week length leg of the expedition. We have a few more real celestial objects along this leg. The legs after this one will be two weeks in length and focus on discovering new noteworthy points of interest in the eastern reaches of the galaxy.

  • Map Reference: NGC 3199 Sector LC-V c2-5
    • POI: NGC 3199
    • NGC 3199, also known as The Banana Nebula is an emission nebula in the Carina constellation region of the sky. It was discovered by James Dunlop in 1826. It was originally thought to be a bow shock of it’s central star WR 18, but has since been determined to have been formed due to the composition of local space, not the star’s movement.

  • Map Reference: OGLE-TR-211
    • POI: OGLE-TR-211b
    • OGLE-TR-211b is a known exoplanet, a hot Jupiter in a very close orbit with it’s parent star OGLE-TR-211. It is estimated to be slightly more massive than Jupiter. at 1.03±0.2 Jupiter masses.
    • SIMBAD Link
    • EDSM Link
  • Map Reference: AG Carinae
    • AG Carinae is luminous blue variable star in the Carinae constellation region of the sky, and is one of the most luminous stars in our galaxy. However, due to it’s distance of roughly 20,000 lightyears from our solar system, all the stellar dust between us and it makes it generally not visible to the naked eye despite how bright of a star it is. The star has a planetary nebula of material that has been ejected from the star. It is in a transitional period going from being a class O supergiant star to becoming a Wolf-Rayet star.

      There has been some recent data grom the Gaia mission however suggesting that AG Carinae may actually be close to our own solar system than the previously believed 20,000 lightyears, but it is still up for debate which value is the accurate value.

  • Map Reference: GU Muscae
    • POI: Nova Muscae 1991
    • GU Muscae, also known as Nova Muscae 1991, as well as GRS 1124-683 is a star system containing a black hole candidate. The system was discovered by both the Russian Granat satellite and Japanese Ginga satellite on January 9, 1991 when the system produced an outburst of x-rays. The black hole is estimated to be 7 times as massive as our sun with a companion star it is taking material from that is three-quarters the mass of our sun. The companions star likely was a more massive star before, but has its outer layers blown away by the supernova that resulted in the creation of the black hole.

CEA 6 Leg 3

There are a few optional waypoints on this leg as well as the two main waypoints. The gaps between waypoints at times have a long distance between them so feel free to explore in those gaps and looks for any other cool points of interest and sights to see that may be suitable for submission to the Galactic Exploration Catalog!

    • POI: Pan-Carina YSO Catalog
    • The PCYC catalog is a survey of 1,439 young stellar objects in the Carina complex. This is one star of many in this region that is listed in game via their PCYC catalog number. This star like many others of this catalog have only been cataloged by this specific survey.

    • POI: Trumpler 14
    • DETWC Tr 14 J104348.8-593236 is a young star in the NGC 3372 cluster. It also appears to be the only DETWC catalog (De Gioia-Eastwood+Throop+Walker+Cudworth) star in the in-game galaxy. I’m adding it as an optional waypoint as a curiosity to see what is there. There are a fair few other real stars in the 2MASS and PCYC catalgs around this star system as well.
    • SIMBAD Link
    • EDSM Link
  • Map Reference: 206 G. Carinae
    • POI: HD 91533
    • This appears to be some sort of mix-up by the stellar forge with information. The main name this is listed as is 206 G. Carinae, however it lists the HIPP as 51623 and HD as 91533. HIP 51623/HD 91533 is a different star than G Carinae, and there is not a star known as 206 Carinae. (The game’s habit of sometimes smashing together a star’s Bayer and Flamsteed designations into one) Additionally GIP 51623 does not have an official Carinae based Flamsteed or Bayer designation at all.

      In any case, the stellar data besides the name does match with HIP 51623, which is a real star in the Alessi 5 open cluster. That said is seems to be the only star from that cluster represented in the in-game galaxy. It is a little under halfway through the distance of the leg.

  • Map Reference: Eta Carinae
    • Eta Carinae is a star system containing at least two known starts, and has a combined luminosity greater than five million times brighter than our Sun. It is roughly 7,500 lightyears from our solar system in the Cairna constellation section of the night sky. In 1837 is brightened to become brighter than Rigel. It then became the second brightest star in the night sky for a few days inMarch 1843 before beginning to fade down again, going below naked eye visibility levels in 1856. It had another short brightening period in 1892 before fading again. It has though since 1940 been brightening consistently and has become a 4.5 magnitude star since 2014.

      The brightness eruptions of this star are unqieu to it and no other anlogues to this behaviour are currently known in any galaxy. The cause of the eruptions is also not known, some hypotheses include one of the stars having mass transfer to the main star on close orbital passes (perriastron passage), or possibly the merging of two very large stars into a single larger star.

Within it is the Carina OB1 association and several open clusters including Trumpler 14 and Trumpler 16. It is one of the largest diffuse nebulae in our night sky. While it is four times as large as and brighter than the Orion Nebula it is less well known due to being in the southern sky. It was discovered in 1752 by Nicolas-Louis de Lacaille.

  • Map Reference: Alnitak
    • POI: Orion’s Belt
    • The easternmost star of Orion’s Belt, a very recognizable landmark in the night sky. It is a known triple-star system. Its distance from our solar system in-game is actually a lot closer than in reality, as when the in-game galaxy was generated it was thought to be at a distance of about 225 parsecs from us, however observations since then have revealed that it is actually much further at approximately 1260 parsecs. (about 4100 lightyears). Alnitak Aa is an O class supergiant, estimated to be roughly 33 times as massive as our sun, 20 times the diameter, and 21,000 times the brightness. It is the brightest class O star in the night sky. – Alnitak Ab is a B type subgiant discovered in 1998, and Alnitak C is believed to be part of the system, but has not been fully confirmed and may be another star along the line of sight from our solar system to Alnitak.

    • SIMBAD Link
    • EDSM Link
  • Map Reference: Mintaka
    • POI: Orion’s Belt
    • The westernmost star of Orion’s Belt, a very recognizable landmark in the night sky. Mintaka is a multi star system approximately 1200 lightyear from our own solar system, however in game it is only 692 lightyears from Sol. This is due to new discoveries that occurred since the generation of the in-game galaxy show it being nearly twice as far as it was believed to be in 2013. – The primary stars of the system are a class O and a class B star that orbit each other. They are aligned such that they eclipse each other periodically as viewed from our solar system, causing periodic decreases in the brightness of the system in the night sky.
