Controversy over the discovery of Haumea

images of Haumea were recorded as early as 1955 at the Palomar Observatory On December 28, 2004, Mike Brown and his team discovered Haumea on images they had taken with the 1.3 m SMARTS Telescope from the Cerro Tololo Inter-American Observatory in Chile at the Palomar Observatory in the United States on May 6, 2004, while looking for what he hoped would be the tenth planet. The Caltech discovery team used the nickname "Santa" among themselves, because they had discovered Haumea on December 28, 2004, just after Christmas. However, it was clearly too small to be a planet, because it was significantly smaller than Pluto, and Brown did not announce the discovery. Instead he kept it under wraps, along with several other large trans-Neptunian objects (TNOs), pending additional observation to better determine their natures. When his team discovered Haumea's moons, they realized that Haumea was more rocky than other TNOs, and that its moons were mostly ice. On July 7, 2005, while he was finishing the paper describing the discovery, Brown's daughter Lilah was born, which delayed the announcement further. On July 20, the Caltech team published an online abstract of a report intended to announce the discovery at a conference the following September. In this Haumea was given the code K40506A. At around that time, Pablo Santos Sanz, a student of José Luis Ortiz Moreno at the Instituto de Astrofísica de Andalucía at Sierra Nevada Observatory in southern Spain, claims to have examined the backlog of photos that the Ortiz team had started taking in December 2002. He says that he found Haumea in late July 2005, on images taken on March 7, 9, and 10, 2003. He further said that in checking whether this was a known object, the team came across Brown's internet summary, describing a bright TNO much like the one they had just found. Googling the reference number for object K40506A on the morning of July 26, they found the Caltech observation logs of Haumea, but according to their account, those logs contained too little information for Ortiz to tell if they were the same object. The Ortiz team also checked with the Minor Planet Center (MPC), which had no record of this object. Wanting to establish priority, they emailed the MPC with their discovery on the night of July 27, 2005, titled "Big TNO discovery, urgent", without making any mention of the Caltech logs. The next morning they again accessed the Caltech logs, including observations from several additional nights. They then asked Reiner Stoss at the amateur Astronomical Observatory of Mallorca for further observations. Stoss found precovery images of Haumea in digitized Palomar Observatory slides from 1955, and located Haumea with his own telescope that night, July 28. Within an hour, The data was published by the MPC on July 29. On July 29, 2005, Haumea was given its first official label, the temporary designation 2003 EL61, with the "2003" based on the date of the Spanish discovery image. On September 7, 2006, it was numbered and admitted into the official minor planet catalogue as (136108) 2003 EL61. ==Reaction to the announcement==

The same day as the MPC publication, Brown's group announced the discovery of another Kuiper belt object, , more distant, brighter and apparently larger than Pluto, as the tenth planet. The announcement was made earlier than planned to forestall the possibility of similar events with that discovery, when the MPC told them that their observational data was publicly accessible, and they realized that not only Haumea data but by that time their Eris data had been publicly accessed. The same day Ortiz announced the discovery of Haumea, Brown submitted his own draft with the data on the first of its moons that he had discovered on January 26, 2005, to The Astrophysical Journal. Brown, though disappointed at being scooped, congratulated the Ortiz team on their discovery. He apologized for immediately overshadowing their announcement of Haumea with his announcement of Eris, and explained that someone had accessed their data and he was afraid of being scooped again. Ortiz did not volunteer to say that it had been he who accessed the data. Upon learning from web server records that it was a computer at the Sierra Nevada Observatory that had accessed his observation logs the day before the discovery announcementlogs which included enough information to allow the Ortiz team to precover Haumea in their 2003 imagesBrown came to suspect fraud. He emailed Ortiz on August 9 and asked for an explanation. Ortiz responded saying that Brown's penchant for "hiding objects" had alienated other astronomers and harmed science (see Timeline of discovery of Solar System planets and their moons to verify typical time scale of observation and publication of discoveries). On August 15 the Caltech team filed a formal complaint with the IAU, accusing the Ortiz team of a serious breach of scientific ethics in failing to acknowledge their use of the Caltech data, and asked the MPC to strip them of discovery status. Ortiz later admitted he had accessed the Caltech observation logs but denied any wrongdoing, stating this was merely part of verifying whether they had discovered a new object. Brown began to wonder if the Spanish team had actually identified Haumea at all before they saw his own abstract and telescope log, noting that Ortiz' team claimed to have sat on their data for a period of 28 months until Brown's upload of his abstract, then coincidentally identified Haumea within the six days prior to accessing his abstract. ==Official naming==

'', which had been proposed as a name for the dwarf planet IAU protocol is that discovery credit for a minor planet goes to whoever first submits a report to the MPC with enough positional data for a decent orbit determination, and that the credited discoverer has priority in naming it. This was Ortiz et al., and they proposed the name Ataecina, an Iberian goddess of the underworld. She is the equivalent of the Roman goddess Proserpina, who was in turn one of Pluto's lovers. in September 2006 the Caltech team submitted formal names from Hawaiian mythology to the IAU for both (136108) 2003 EL61 and its moons, in order "to pay homage to the place where the satellites were discovered". The names were proposed by David Rabinowitz of the Caltech team. Haumea is the tutelary goddess of the island of Hawaii, where the Mauna Kea Observatory is located. In addition, she is identified with Papa, the goddess of the earth and wife of Wākea (space), which is appropriate because 2003 EL61 is thought to be composed almost entirely of solid rock, without the thick ice mantle over a small rocky core typical of other known Kuiper belt objects. Lastly, Haumea is the goddess of fertility and childbirth, with many children who sprang from different parts of her body; At the CSBN, the outcome of the voting was very close, ==Aftermath==

Brian G. Marsden, head of the MPC at Harvard who had supported Brown on previous naming disputes, again supported Brown, saying that "Sooner or later, posterity will realise what happened, and Mike Brown will get the full credit". The Ortiz team objected, suggesting that if Ataecina were not accepted the IAU could at least have chosen a third name favoring neither party, and accusing the IAU of political bias. Rumors appeared that Dagda, the name of a god from Irish mythology and a "neutral" name, was indeed proposed by a member of the CSBM but was not used in the end. Ortiz went on to say "I am not happy, I think the [IAU] decision is unfortunate and sets a bad precedent." Immediately after the announcement of the name, Brown noted that it is unusual to be allowed to name an object without being acknowledged as its official discoverer but declared that he is pleased with the outcome and that he "think[s] this is as good a resolution as we'll get". ==References==
