Meeting Update Apr.30

  • Star Formation: had a two hour discussion with Eric last Friday. There were some good new ideas and at the end we agreed that the phenomenon observed can be possible but need to be further verified. One idea we discussed is that the explosion happened on both sides of the bowshock (both expansions have a halo like feature, but the expansion on the righthand side is delayed) can be triggered by depressuring the two different regions. The lefthand side expansion can be triggered by the runaway outer halo (the spherical expansion is possible based on approximate calculation that the incoming flow from right to left resulted from colliding flows missing the star has similar Ram pressure compared to the incoming wind but much higher thermal pressure), the righthand side expansion can be triggered by the region not centered at the star but actually displaced to the right, where compression is highest (converging flow coming from the back of the clump, the incoming colliding flow attracted by the core but miss the star). I am currently making new plots according to our discussion.
  • Krumholz accretion: fixed the way how the particle is initialized (basically, the original Krumholz accretion forms zero mass particles and the accretion rate is depend on the particle mass). A new restart run with fixed Krumholz accretion Mach = 1.5 triggered star formation is submitted.
  • Resistive Paper: finished By Rm = 10 run, one run left (Bx Rm = 10). The paper will feature Rm = infinite, 300, 30, 10 runs for both Bx and By.
