Molecular bullets in the planetary nebula BD+30 degrees 3639

We report high resolution (1." 0 x 0." 5) CO line imaging of the compact pl anetary nebula BD+30 degrees 3639 that reveals a remarkable pair of high-ve locity, molecular knots, or "bullets". These bullets are similar to 1 " in size, and are symmetrical about the central star in position (+/- 3 " at P. A. similar to 22 degrees) and in velocity (+/- 50 km s(-1)). The mass of ea ch bullet is greater than or similar to 7 x 10(-4) M. and their kinematic a ge is similar to 500 yr. The high velocity and symmetry of these structures indicate underlying bipolar jets from the central star that interact with the surrounding neutral gas. The unexpected presence of the bullets in BD+3 0 degrees 3639 strengthens the idea that jets are common and play a crucial role in the shaping of planetary nebulae.
