Information: - A nebula (Latin for "cloud"; pl. nebulae, nebul, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, "nebula" was a name for any diffuse astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was once referred to as the "Andromeda Nebula" (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble and others. - HD 205739 b is an extrasolar planet located approximately 350 light-years away in the constellation of Piscis Austrinus, orbiting the star HD 205739. This planet has a minimum mass 37% more than Jupiter and orbits 90% of the distance between the Earth and the Sun. The planet has a very elliptical orbit, which has led its discoverers to postulate that the planet's surface temperature varies by about 100 K along the entire orbit. This planet was reported on September 5, 2008 after its discovery at Las Campanas Observatory, where the planet was observed for years by the N2K Consortium while using the Magellan Telescopes. Follow-up observations collected the radial velocity measurements necessary to confirm the candidate as a planet. - In astronomy and physical cosmology, the metallicity or Z is the fraction of mass of a star or other kind of astronomical object that is not in hydrogen (X) or helium (Y). Most of the physical matter in the universe is in the form of hydrogen and helium, so astronomers use the word "metals" as a convenient short term for "all elements except hydrogen and helium". This usage is distinct from the usual physical definition of a solid metal. The rationale for the astronomical usage is that in the high-temperature and pressure environment of a star, atoms do not undergo chemical reactions and effectively have no chemical properties, including that of being a metal as usually understood. For example, stars and nebulae with relatively high abundances of carbon, nitrogen, oxygen, and neon are called "metal-rich" in astrophysical terms, even though those elements are non-metals in chemistry. - HD 154672 b is an extrasolar planet located approximately 210 light-years away in the constellation of Ara, orbiting the metal-rich and aged star HD 154672. This planet has a minimum mass five times that of Jupiter and orbits at about 60% the distance between the Earth to the Sun. Its orbit is very elliptical, which causes temperatures on the planet to vary significantly as it proceeds along its orbit. This planet was discovered in Las Campanas Observatory on September 5, 2008 using the radial velocity method (Doppler spectroscopy). Along with HD 205739 b, the planets were the first to be discovered by the N2K Consortium using the Magellan Telescopes. - HD 154672 is a yellow subgiant ( spectral type G3 IV ) . It is about 65 parsecs away from the Sun that is larger than , but of a similar mass to , the Sun. However , HD 154672 is much older . The star is very metal - rich , which is one of the reasons why it was targeted for a planet search by the N2K Consortium , which discovered the gas giant planet HD 154672 b using Doppler Spectroscopy ; the discovery was reported in October 2008 . The N2K collaboration chose HD 154672 primarily because it aimed to discover the correlation between a star 's metallicity and the mass of orbiting planets . HD 154672 was targeted by the Magellan Telescopes . It is the host of the first planet discovered from the telescopes by N2K . Given the information above, choose from the list below the object entity that exhibits the relation 'constellation' with the subject 'hd 154672'. Choices: - andromeda - ara - piscis austrinus

Information: - A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan. In the United Kingdom and Ireland, county towns have a similar function. - Accomack County is a United States county located in the eastern edge of the Commonwealth of Virginia. Together, Accomack and Northampton counties make up the Eastern Shore of Virginia, which in turn is part of the Delmarva Peninsula, bordered by the Chesapeake Bay and the Atlantic Ocean. The Accomack county seat is the town of Accomac. - The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". - The Eastern Shore of Virginia consists of two counties (Accomack and Northampton) on the Atlantic coast of the Commonwealth of Virginia in the United States. The region is part of the Delmarva Peninsula and is separated from the rest of Virginia by the Chesapeake Bay. Its population was 45,553 as of 2010. - The Chesapeake Bay is an estuary lying inland from the Atlantic Ocean, and surrounded by the North American mainland to the west, and the Delmarva Peninsula to the east. It is the largest such body in the contiguous United States. The northern bay is within Maryland, the southern portion within Virginia, and is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) plus all of the District of Columbia. - Wessells Root Cellar is a small brick structure near Hallwood , Accomack County , Virginia . The cellar was built sometime after 1768 by William Vessells as a structure separate from the main house , which burned in 1937 . The cellar is of fine quality and has remained in the Wessells family for more than two hundred years . A decorative header pattern in the gable using overfired brick is an unusual detail . - The Delmarva Peninsula, or simply Delmarva, is a large peninsula on the East Coast of the United States, occupied by most of Delaware as well as the Eastern Shore of Maryland and the Eastern Shore of Virginia. Although called a peninsula, it is technically an island after the digging of the Chesapeake and Delaware Canal. The peninsula is long. In width, it ranges from near its center, to at the isthmus on its northern edge, to less near its southern tip of Cape Charles. It is bordered by the Chesapeake Bay on the west, the Delaware River, Delaware Bay, and the Atlantic Ocean on the east, and the Elk River and its isthmus on the north.
