An upper limit on gas production from 3200 Phaethon
Asteroid 3200 Phaethon resembles a comet in some ways, including a highly-eccentric orbit (e∼ 0.89) and a strong associated meteor shower (the Geminids). Yet this object has never been observed to exhibit any cometary activity, i.e., gas production. We observed 3200 Phaethon with the Caltech Submillimeter Observatory on two occasions, once while it was near its closest approach to Earth as it n...
متن کاملSearch for Activity in 3200 Phaethon
We present deep optical imaging of Geminid meteor stream parent 3200 Phaethon taken in search of low-level cometary activity (i.e., coma or dust trail). Although no unambiguous cometary behavior was observed, we find an upper limit on the object’s cometary mass-loss rate of Ṁlim 0:01 kg s . The corresponding active fraction (the fraction of the surface area that could consist of freely sublimat...
متن کاملRecurrent Perihelion Activity in (3200) Phaethon
We present a study of planet-crossing asteroid (3200) Phaethon at three successive perihelia in 2009, 2010, and 2012, using the NASA STEREO spacecraft. Phaethon is clearly detected in 2009 and 2012, but not in 2010. In both former years, Phaethon brightened unexpectedly by ∼1 mag at large phase angles, inconsistent with the ∼1 mag of steady fading expected from a discrete, macroscopic body over...
متن کاملBiofertilizer production from gas refinery wastewater
Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...
متن کاملAn Upper Limit on the Abundance of Small
I describe the detection of 201 highly significant dips in the count rate of Sco X-1 from a search of some 500 ks of archival RXTE PCA data, which could be caused by TNO occultations. I show that most of these dips are correlated with particle showers in the PCA, suggesting that the dips in count rate result from large amounts of charge built up in the detectors. From the distribution of partic...
