Vaquita (pronounced Va-ki-ta) are a rare species of porpoise (Phocoena sinus) endemic to the Gulf of Mexico. The Vaquita, being the most endangered Cetacean in our world, have drawn much attention by the Mexican Cousteau Society, other multi-national environmental groups, and our Sonrisa Net members because they are being killed off by illegal fishing and are almost extinct as there are only about 90-100 remaining in the northern part of the Sea of Cortez. In addition, the Viquita have characteristics of being small, elusive, and rarely seen. We believe this a fitting name for this host star (18 Del) as it is located in Delphinus and a member of the Heavenly Waters family. Delpinus is also one of the smallest constellation (69th of 88) as is the Vaquita is small compared to its much large dolphin cousins.

Leslie Peltier (1900-1980) was recognized by Harlow Shapley as the “the world’s greatest nonprofessional astronomer”. During his 64 years of continuous observing he discovered 12 comets, 4 novae and submitted 132,000 variable star observations to AAVSO, of which he was a member. The Leslie C. Peltier award is given by the Astronomical League to honor an amateur astronomer who has contributed observations of lasting significance. Leslie received the Ohio Author of the Year award in 1966 for his book, “Starlight Nights”. Comet hunter David Levy, commenting on this book states “Many books explain how to observe the sky; Starlight Nights explains why.” This autobiographical account describes Leslie’s first introduction to the Pleiades by his mother when he was five years old. As a teen, he picked strawberries to earn enough money to purchase his first telescope, a 2 inch refractor. In honor of his outstanding observations and contributions he was loaned a 4 inch scope by AAVSO in 1919 and in 1925, Henry Norris Russell arranged for him to have use of a 6 inch refractor from Princeton University. When the observatory at Miami of Ohio University was being disassembled in 1959, Leslie was gifted a 12” Clark Refractor. Mr. Peltier was born in Delphos Ohio and lived there his entire life where he had everything he needed; his family, home, gardens and observatory. For this reason, in his honor, we would like to nominate the name Peltier for the exoplanet host star now known as 18 Delphinis.

Nie Er
Delphinus is a beautiful constellation with a shape of dolphin. In ancient Greek mythology, Arion was a famous poet and musician who had been kidnapped by pirates and rescued by a dolphin. In the folktale, the dolphin was moved by Arion’s song and thus saved his life. Nie Er (1912-1935) is a brilliant Chinese musician who was born in a poverty-stricken family and learned flute, violin and piano by himself. In his very short life, Nie Er composed 37 movements, mainly focusing on the improvement of Chinese laborers’ life condition. At the age of 23, Nie Er drowned in the Pacific Ocean when swimming, which reminds us of Arion.

Around 600 B.C. the Greeks were colonizing the whole Mediterranean region, they landed on an wild island, lacking of about everything, uncultivated. They establish trading posts, develop agriculture. They will call this island Kalliste, meaning in ancient greek « the most beautiful ». Like the Greeks landing on new lands, we must imagine Earthlings arriving near this star in the constellation Delphinus, and be getting closer and closer, being amazed by the beauty of that star. By remembering the discoveries of the Greeks, who have been scouring the Mediterranean Sea, they will also give this star the name Kalliste. This solar system from the constellation Delphinus with its only one planet will be a reference to Mare Nostrum, the birthplace of our civilization.

Abu Bakr Muhammad Ibn-Yhaya ibn-al-Saigh al-Tujibi ibn-Bajja al-Andalusi al-Saraqusti, born in Saragossa (Spain), and died in Fes (Morocco) in 1139, was one of the most important philosophers of Muslim Spain and a pivotal figure in the transmission of greek science into the islamic world, in the forefront of the 12th century andalusian movement to criticize and replace ptolemaic astronomy based on aristotelian principles. In addition to astronomy, he was also active in other scientific disciplines, such as mathematics, botany, pharmacology, and medicine. The importance of Ibn-Bajja's astronomy lies in the fact that he seems to have been the first of the Andalusians to develop a criticism of Ptolemy based on philosophical tenets (the others being Ibn-Tufail, Ibn-Rushd and Bitruji). They wished to formulate a cosmos according to aristotelian principles (uniform and circular motions centered on the Earth) in which planetary models had no need of eccentrics and epicycles. According to Maimonides in The Guide of the Perplexed, Ibn-Bajja accepted eccentrics but not epicycles. On the subject of Mercury, he disagrees with the andalusian astronomer Zarqali, who formulated some alternative models to Ptolemy. Besides, in his commentary to Aristotle's Physics, Ibn-Bajja introduces a digression following Philoponus in which he accepts the existence of epicycles. However, a short and incomplete treatise has survived entitled "Kalam fi al‐hayaa" (Discourse on cosmology) that criticizes Ptolemy's method. Here, on the basis of aristotelian logic, Ibn-Bajja tackles the problem of the relationship between what the astronomer can observe and the underlying reality and argues that the planetary models of the ptolemaic astronomers do not fit the tenets of aristotelian scientific method.
