Page 4 May 12, 2016 Local Tracksters Advance to CIF Prelims having fewer misses. Both move on to the Southern Section Division II Prelims. Kiyaam Cooksey captured the 110-meter high hurdles clocking 15.03 and took second in the 300 intermediates in 39.94 to qualify for CIF in both events. Jonathan Blackman was second in the 100-meter dash timing 11.13 and finished fourth in the 200 in 21.87 seconds. Lawndale’s 4x100-meter and 4x400 relays both recorded second place finshes. Its 400 relay squad of Cooksey, Blackman, Perkinson and Demarjae Gilmore was clocked at 43.89 to finish behind winner Culver City (43.11). Closing the meet, the Cardinals 1,600 relay team of Cooksey, Jona Hian, Willis and Jacob Khu placed second at 3:26.94. Santa Monica, behind nationally ranked 400-meter runner Marcel Espinoza, won the race clocking 3:26.17. Espinoza also won the 200 and 400 in the meet. For the girls, Lawndale’s Destiny Jones advanced after taking third in the high jump, By Joe Snyder Last week was the CIF-Southern Section League Track and Field Championship Week and several local athletes were able to place high enough with good enough marks or times to advance to this week’s Southern Section Prelims to be held at various sites. In the Ocean League Championships last Thursday at Culver City High, Lawndale had some league champions, behind Jaelin Walker who won the long jump and high jump. Walker captured the long jump with a very good leap of 22 feet, three and a half inches and the high jump at five feet, 10 inches. Walker also placed third in the triple jump at 41-7. Bryant Perkinson was able to defend his league title in the triple jump at 43-9. He also finished second in the long jump with a leap of 22-2 and made the Southern Section Division II Prelims in both events. Erick Willis, along with Walker, had a 5-10 high jump but had to settle for a second place due to Walker leaping 4-8. The Lady Cardinals also had a second place finish by Ashley Calloway in the shot put with a toss of 30-4. Teammate Kimberly Romero was third at 29-9. El Segundo’s Tatiana Taylor won the event throwing 33-4. “We’re hoping to send athletes in at least four events to the championship meet,” Lawndale High assistant coach Demitre Howard said. “We had a few close losses. Our boys took second (behind champion Santa Monica) in league. Honestly our kids excelled. We lost some close dual meets. (The Cardinals took third, behind first place Santa Monica and runner-up Culver City in the Ocean League.)” Hawthorne High’s best showing was by Kishawn Berry in the boys’ 100-meter dash where he finished third timing 11.43 but it was not good enough to qualify for the CIFSouthern Section Division II Prelims. Culver City’s Chalil Hooper won the 100 in 11.0, followed by Blackman. The Southern Section Division II Prelims will be at Moorpark High, starting at 8 a.m. Saturday. The finishers in each event move on to the Southern Section Divisional Championships on May 21 at Cerritos College with the field events beginning at 11 a.m. and the running events at 1 p.m. Bay League Morningside’s boys and Inglewood’s girls had a few top showings in last Friday’s Bay League Track and Field Championships at Redondo High. Keying the Monarchs was Adarrus Wilson. Wilson won the 100-meter dash at 11.12 seconds and was a close second behind Redondo’s Jerone Jackson clocking 22.66 in the 200. Jackson won the 200 in 22.64. The Monarchs also had a league champion by Darren Morgan in the high jump at 6-4. All move on to the CIF-Southern Section Division IV Prelims at Estancia High in Costa Mesa Saturday, beginning at 8 a.m. For the Lady Sentinels, sophomore Tajanae Nettles placed second in the 400 timing 59.07. Winning the race was Mira Costa’s Jaylah Herron in 57.83. Nettles also helped Inglewood’s 4x100-meter relay finish second (also behind Mira Costa) clocking 49.31. The Mustangs won the race at 48.91. Nettles and the relay move on to the CIF-Southern Section Division III Prelims Saturday at 8 a.m. at Trabuco Hills High in Mission Viejo. All divisional finals are at Cerritos College, beginning 11 a.m. on May 21. Culver City Sweeps Hawthorne Hawthorne High’s baseball team found first place Culver City too much to handle as the Centaurs easily sweep the Cougars last week. At Culver on May 3, the Centaurs rolled over the Cougars 9-2. At Hawthorne last Thursday, Culver blanked the Cougars 8-0. On May 3, Brandon Brown drove in a run with a base hit. Daniel Sanchez tripled and scored a run. The Cougars, who fell to 1-7 in the Ocean League, have a league rivalry two-game series against Lawndale this week. After visiting the Cardinals last Tuesday, Hawthorne hosts Lawndale today at 3:15 p.m. • Morningside High’s Adarrus Wilson pulls ahead as he heads to win the 100-meter dash in 11.12 seconds at last Friday’s Bay League Track and Field Championships.

And since the Sun formed in a star cluster with several thousand neighbors, such stellar encounters were more common in the early history of our solar system. However, an interloping star is more likely to pull Planet Nine away completely and eject it from the solar system. Li and Adams Looking Up Planet Nine: A World that Shouldn’t Exist By Bob Eklund Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. Since then theorists have puzzled over how this planet could end up in such a distant orbit. New research by astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) examines a number of scenarios and finds that most of them have low probabilities. Therefore, the presence of Planet Nine remains a mystery. “The evidence points to Planet Nine existing, but we can’t explain for certain how it was produced,” says CfA astronomer Gongjie Li, lead author on a paper accepted for publication in the Astrophysical Journal Letters. Planet Nine circles our Sun at a distance of about 40 billion to 140 billion miles. This places it far beyond all the other planets in our solar system. The question becomes: did it form there, or did it form elsewhere and land in its unusual orbit later? Li and her co-author Fred Adams (University of Michigan) conducted millions of computer simulations in order to consider three possibilities. The first and most likely find only a 10 percent probability, at best, of Planet Nine landing in its current orbit. Moreover, the planet would have had to start at an improbably large distance to begin with. CfA astronomer Scott Kenyon believes he may have the solution to that difficulty. In two papers submitted to the Astrophysical Journal, Kenyon and his co-author Benjamin Bromley (University of Utah) use computer simulations to construct plausible scenarios for the formation of Planet Nine in a wide orbit. “The simplest solution is for the solar system to make an extra gas giant,” says Kenyon. They propose that Planet Nine formed much closer to the Sun and then interacted with the other gas giants, particularly Jupiter and Saturn. A series of gravitational kicks then could have boosted the planet into a larger and more elliptical orbit over time. “Think of it like pushing a kid on a swing. If you give them a shove at the right time, over and over, they’ll go higher and higher,” explains Kenyon. “Then the challenge becomes not shoving the planet so much that you eject it from the solar system.” That could be avoided by interactions with the solar system’s gaseous disk, he suggests. Kenyon and Bromley also examine the possibility that Planet Nine actually formed at a great distance to begin with. They find that the right combination of initial disk mass and disk lifetime could potentially create Planet Nine in time for it to be nudged by Li’s passing star. “The nice thing about these scenarios is that they’re observationally testable,” Kenyon points out. “A scattered gas giant will look like a cold Neptune, while a planet that formed in place will resemble a giant Pluto with no gas.” •
